Subject: [PATCH 001/203] ARM: mvebu: Add support for USB storage class in
mvebu_defconfig
Some boards can have built-in USB storage class controllers so
it's better to have this option included by default.
Currently this option is needed to support built-in USB MMC controller
found in Globalscale Mirabox board.

Subject: [PATCH 003/203] ARM: mvebu: Add support for NOR flash device on
Armada XP-DB board
The Armada XP Development Board (DB-78460-BP) has a NOR flash device
connected to the Device Bus. This commit adds the device tree node
to support this device.
This SoC supports a flexible and dynamic decoding window allocation
scheme; but since this feature is still not implemented we need
to specify the window base address in the device tree node itself.
This base address has been selected in a completely arbitrary fashion.

Subject: [PATCH 004/203] of/pci: Provide support for parsing PCI DT ranges
property
This patch factors out common implementation patterns to reduce overall kernel
code and provide a means for host bridge drivers to directly obtain struct
resources from the DT's ranges property without relying on architecture specific
DT handling. This will make it easier to write archiecture independent host bridge
drivers and mitigate against further duplication of DT parsing code.
This patch can be used in the following way:
struct of_pci_range_parser parser;
struct of_pci_range range;
if (of_pci_range_parser_init(&parser, np))
; //no ranges property
for_each_of_pci_range(&parser, &range) {
/*
directly access properties of the address range, e.g.:
range.pci_space, range.pci_addr, range.cpu_addr,
range.size, range.flags
alternatively obtain a struct resource, e.g.:
struct resource res;
of_pci_range_to_resource(&range, np, &res);
*/
}
Additionally the implementation takes care of adjacent ranges and merges them
into a single range (as was the case with powerpc and microblaze).

clocks a child of the other, as we did for the sataX and sataXlnk
clocks on Armada XP.

Subject: [PATCH 008/203] clk: mvebu: add more PCIe clocks for Armada XP
The current revision of the datasheet only mentions the gatable clocks
for the PCIe 0.0, 0.1, 0.2 and 0.3 interfaces, and forgot to mention
the ones for the PCIe 1.0, 1.1, 1.2, 1.3, 2.0 and 3.0
interfaces. After confirmation with Marvell engineers, this patch adds
the missing gatable clocks for those PCIe interfaces.
It also changes the name of the previously existing PCIe gatable
clocks, in order to match the naming using the datasheets.

Subject: [PATCH 013/203] drivers: memory: Introduce Marvell EBU Device Bus
driver
Marvell EBU SoCs such as Armada 370/XP, Orion5x (88f5xxx) and
Discovery (mv78xx0) supports a Device Bus controller to access several
kinds of memories and I/O devices (NOR, NAND, SRAM, FPGA).
This commit adds a driver to handle this controller. So far only
Armada 370, Armada XP and Discovery SoCs are supported.
The driver must be registered through a device tree node;
as explained in the binding document.
For each child node in the device tree, this driver will:
* set timing parameters
* register a child device
* setup an address decoding window, using the mbus driver
Keep in mind the address decoding window setup is only a temporary hack.
This code will be removed from this devbus driver as soon as a proper device
tree binding for the mbus driver is added.

+Device tree bindings for MVEBU Device Bus controllers
+
+The Device Bus controller available in some Marvell's SoC allows to control
+different types of standard memory and I/O devices such as NOR, NAND, and FPGA.
+The actual devices are instantiated from the child nodes of a Device Bus node.
+
+Required properties:
+
+ - compatible: Currently only Armada 370/XP SoC are supported,
+ with this compatible string:
+
+ marvell,mvebu-devbus
+
+ - reg: A resource specifier for the register space.
+ This is the base address of a chip select within
+ the controller's register space.
+ (see the example below)
+
+ - #address-cells: Must be set to 1
+ - #size-cells: Must be set to 1
+ - ranges: Must be set up to reflect the memory layout with four
+ integer values for each chip-select line in use:
+ 0 <physical address of mapping> <size>
+
+Mandatory timing properties for child nodes:
+
+Read parameters:
+
+ - devbus,turn-off-ps: Defines the time during which the controller does not
+ drive the AD bus after the completion of a device read.
+ This prevents contentions on the Device Bus after a read
+ cycle from a slow device.
+
+ - devbus,bus-width: Defines the bus width (e.g. <16>)
+
+ - devbus,badr-skew-ps: Defines the time delay from from A[2:0] toggle,
+ to read data sample. This parameter is useful for
+ synchronous pipelined devices, where the address
+ precedes the read data by one or two cycles.
+
+ - devbus,acc-first-ps: Defines the time delay from the negation of
+ ALE[0] to the cycle that the first read data is sampled
+ by the controller.
+
+ - devbus,acc-next-ps: Defines the time delay between the cycle that
+ samples data N and the cycle that samples data N+1
+ (in burst accesses).
+
+ - devbus,rd-setup-ps: Defines the time delay between DEV_CSn assertion to
+ DEV_OEn assertion. If set to 0 (default),
+ DEV_OEn and DEV_CSn are asserted at the same cycle.
+ This parameter has no affect on <acc-first-ps> parameter
+ (no affect on first data sample). Set <rd-setup-ps>
+ to a value smaller than <acc-first-ps>.
+
+ - devbus,rd-hold-ps: Defines the time between the last data sample to the
+ de-assertion of DEV_CSn. If set to 0 (default),
+ DEV_OEn and DEV_CSn are de-asserted at the same cycle
+ (the cycle of the last data sample).
+ This parameter has no affect on DEV_OEn de-assertion.
+ DEV_OEn is always de-asserted the next cycle after
+ last data sampled. Also this parameter has no
+ affect on <turn-off-ps> parameter.
+ Set <rd-hold-ps> to a value smaller than <turn-off-ps>.
+
+Write parameters:
+
+ - devbus,ale-wr-ps: Defines the time delay from the ALE[0] negation cycle
+ to the DEV_WEn assertion.
+
+ - devbus,wr-low-ps: Defines the time during which DEV_WEn is active.
+ A[2:0] and Data are kept valid as long as DEV_WEn
+ is active. This parameter defines the setup time of
+ address and data to DEV_WEn rise.
+
+ - devbus,wr-high-ps: Defines the time during which DEV_WEn is kept
+ inactive (high) between data beats of a burst write.
+ DEV_A[2:0] and Data are kept valid (do not toggle) for
+ <wr-high-ps> - <tick> ps.
+ This parameter defines the hold time of address and
+ data after DEV_WEn rise.
+
+ - devbus,sync-enable: Synchronous device enable.
+ 1: True
+ 0: False
+
+An example for an Armada XP GP board, with a 16 MiB NOR device as child
+is showed below. Note that the Device Bus driver is in charge of allocating
+the mbus address decoding window for each of its child devices.
+The window is created using the chip select specified in the child
+device node together with the base address and size specified in the ranges
+property. For instance, in the example below the allocated decoding window
+will start at base address 0xf0000000, with a size 0x1000000 (16 MiB)
+for chip select 0 (a.k.a DEV_BOOTCS).
+
+This address window handling is done in this mvebu-devbus only as a temporary
+solution. It will be removed when the support for mbus device tree binding is
+added.
+
+The reg property implicitly specifies the chip select as this:
+
+ 0x10400: DEV_BOOTCS
+ 0x10408: DEV_CS0
+ 0x10410: DEV_CS1
+ 0x10418: DEV_CS2
+ 0x10420: DEV_CS3
+
+Example:
+
+ devbus-bootcs@d0010400 {
+ status = "okay";
+ ranges = <0 0xf0000000 0x1000000>; /* @addr 0xf0000000, size 0x1000000 */
+ #address-cells = <1>;
+ #size-cells = <1>;

Subject: [PATCH 015/203] pci: mvebu: no longer fake the slot location of
downstream devices
By default, the Marvell hardware, for each PCIe interface, exhibits
the following devices:
* On slot 0, a "Marvell Memory controller", identical on all PCIe
interfaces, and which isn't useful when the Marvell SoC is the PCIe
root complex (i.e, the normal case when we run Linux on the Marvell
SoC).
* On slot 1, the real PCIe card connected into the PCIe slot of the
board.
So, what the Marvell PCIe driver was doing in its PCI-to-PCI bridge
emulation is that when the Linux PCI core was trying to access the
device in slot 0, we were in fact forwarding the configuration
transaction to the device in slot 1. For all other slots, we were
telling the Linux PCI core that there was no device connected.
However, new versions of bootloaders from Marvell change the default
PCIe configuration, and make the real device appear in slot 0, and the
"Marvell Memory controller" in slot 1.
Therefore, this commit modifies the Marvell PCIe driver to adjust the
PCIe hardware configuration to make sure that this behavior (real
device in slot 0, "Marvell Memory controller" in slot 1) is the one
we'll see regardless of what the bootloader has done. It allows to
remove the little hack that was forwarding configuration transactions
on slot 0 to slot 1, which is nice.

Subject: [PATCH 016/203] pci: mvebu: allow the enumeration of devices beyond
physical bridges
Until now, the Marvell PCIe driver was only allowing the enumeration
of the devices in the secondary bus of the emulated PCI-to-PCI
bridge. This works fine when a PCIe device is directly connected into
a PCIe slot of the Marvell board.
However, when the device connected in the PCIe slot is a physical PCIe
bridge, beyond which a real PCIe device is connected, it no longer
worked, as the driver was preventing the Linux PCI core from seeing
such devices.
This commit fixes that by ensuring that configuration transactions on
subordinate busses are properly forwarded on the right PCIe interface.
Thanks to this patch, a PCIe card beyond a PCIe bridge, itself beyond
the emulated PCI-to-PCI bridge is properly detected, with the
following layout:
-[0000:00]-+-01.0-[01]----00.0
+-09.0-[02-07]----00.0-[03-07]--+-01.0-[04]--
| +-05.0-[05]--
| +-07.0-[06]--
| \-09.0-[07]----00.0
\-0a.0-[08]----00.0
Where the PCIe interface that sits beyond the emulated PCI-to-PCI
bridge at 09.0 allows to access the secondary bus 02, on which there
is a PCIe bridge that allows to access the 3 to 7 busses, that are
subordinates to this bridge. And on one of this bus (bus 7), there is
one real PCIe device connected.

Subject: [PATCH 017/203] pci: mvebu: fix the emulation of the status register
The status register of the PCI configuration space of PCI-to-PCI
bridges contain some read-only bits, and so write-1-to-clear bits. So,
the Linux PCI core sometimes writes 0xffff to this status register,
and in the current PCI-to-PCI bridge emulation code of the Marvell
driver, we do take all those 1s being written. Even the read-only bits
are being overwritten.
For now, all the read-only bits should be emulated to have the zero
value.
The other bits, that are write-1-to-clear bits are used to report
various kind of errors, and are never set by the emulated bridge, so
there is no need to support this write-1-to-clear bits mechanism.
As a conclusion, the easiest solution is to simply emulate this status
register by returning zero when read, and ignore the writes to it.
This has two visible effects:
* The devsel is no longer 'unknown' in, i.e
Flags: bus master, 66MHz, user-definable features, ?? devsel, latency 0
becomes:
Flags: bus master, 66MHz, user-definable features, fast devsel, latency 0
in lspci -v.
This was caused by a value of 11b being read for devsel, which is
an invalid value. This 11b value being read was due to a previous
write of 0xffff into the status register.
* The capability list is no longer broken, because we indicate to the
Linux PCI core that we don't have a Capabilities Pointer in the PCI
configuration space of this bridge. The following message is
therefore no longer visible in lspci -v:
Capabilities: [fc] <chain broken>

Subject: [PATCH 018/203] arm: mvebu: fix length of SATA registers area in
.dtsi
The length of the registers area for the Marvell 370/XP SATA
controller was incorrect in the .dtsi: 0x2400 while it should have
been 0x5000. Until now, this problem wasn't noticed because there was
a large static mapping for all I/Os set up by ->map_io(). But since
we're going to get rid of this static mapping, we need to ensure that
the register areas are properly sized.

Subject: [PATCH 019/203] arm: mvebu: fix length of Ethernet registers area in
.dtsi
The length of the registers area for the Marvell 370/XP Ethernet
controller was incorrect in the .dtsi: 0x2400 while it should have
been 0x4000. Until now, this problem wasn't noticed because there was
a large static mapping for all I/Os set up by ->map_io(). But since
we're going to get rid of this static mapping, we need to ensure that
the register areas are properly sized.

Subject: [PATCH 020/203] net: mvneta: read MAC address from hardware when
available
This patch improves the logic used by the mvneta driver to find a MAC
address for a particular interface. Until now, it was only looking at
the Device Tree, and if no address was found, was falling back to
generating a random MAC address.
This patch adds the intermediate solution of reading the MAC address
from the hardware registers, in case it has been set by the
bootloader. So the order is now:
1) MAC address from the Device Tree
2) MAC address from the hardware registers
3) Random MAC address
This requires moving the MAC address initialization a little bit later
in the ->probe() code, because it now requires the hardware registers
to be remapped.

Subject: [PATCH 021/203] arm: mvebu: armada-xp-db: ensure PCIe range is
specified
The ranges DT entry needed by the PCIe controller is defined at the
SoC .dtsi level. However, some boards have a NOR flash, and to support
it, they need to override the SoC-level ranges property to add an
additional range. Since PCIe and NOR support came separately, some
boards were not properly changed to include the PCIe range in their
ranges property at the .dts level.
This commit fixes those platforms.

Subject: [PATCH 024/203] arm: mvebu: remove dependency of SMP init on static
I/O mapping
The ->smp_init_cpus() function is called very early during boot, at a
point where dynamic I/O mappings are not yet possible. However, in the
Armada 370/XP implementation of this function, we have to get the
number of CPUs. We used to do that by accessing a hardware register,
which requires relying on a static I/O mapping set up by
->map_io(). Not only this requires hardcoding a virtual address, but
it also prevents us from removing the static I/O mapping.
So this commit changes the way used to get the number of CPUs: we now
use the Device Tree, which is a representation of the hardware, and
provides us the number of available CPUs. This is also more accurate,
because it potentially allows to boot the Linux kernel on only a
number of CPUs given by the Device Tree, instead of unconditionally on
all CPUs.
As a consequence, the coherency_get_cpu_count() function becomes no
longer used, so we remove it.

Subject: [PATCH 025/203] arm: mvebu: avoid hardcoded virtual address in
coherency code
Now that the coherency_get_cpu_count() function no longer requires a
very early mapping of the coherency unit registers, we can avoid the
hardcoded virtual address in coherency.c. However, the coherency
features are still used quite early, so we need to do the of_iomap()
early enough, at the ->init_timer() level, so we have the call of
coherency_init() at this point.
Unfortunately, at ->init_timer() time, it is not possible to register
a bus notifier, so we add a separate coherency_late_init() function
that gets called as as postcore_initcall(), when bus notifiers are
available.

Subject: [PATCH 026/203] arm: mvebu: move cache and mvebu-mbus initialization
later
Current, the L2 cache and the mvebu-mbus drivers are initialized at
->init_early() time. However, at ->init_early() time, ioremap() only
works if a static I/O mapping has already been put in place. If it's
not the case, it tries to do a memory allocation with kmalloc() which
is not possible so early at this stage of the initialization.
Since we want to get rid of the static I/O mapping, we cannot
initialize the L2 cache driver and the mvebu-mbus driver so early. So,
we move their initialization to the ->init_time() level, which is
slightly later (so ioremap() works properly), but sufficiently early
to be before the call of the ->smp_prepare_cpus() hook, which creates
an address decoding window for the BootROM, which requires the
mvebu-mbus driver to be properly initialized.

Subject: [PATCH 027/203] arm: mvebu: remove hardcoded static I/O mapping
Now that we have removed the need of the static I/O mapping for early
initialization reasons, and fixed the registers area length that were
broken, we can get rid of the static I/O mapping. Only the earlyprintk
mapping needs to be set up, using the debug_ll_io_init() helper
function.

Now that the coherency_init() function is called a bit earlier, we can
actually read the physical address of the coherency unit registers
from the Device Tree, and communicate that to the headsmp.S code,
which avoids hardcoding a physical address.

Subject: [PATCH 029/203] arm: mvebu: don't hardcode the physical address for
mvebu-mbus
Since the mvebu-mbus driver doesn't yet have a DT binding (and this DT
binding may not necessarily be ready for 3.11), the physical address
of the mvebu-mbus registers are currently hardcoded. This doesn't play
well with the fact that the internal registers base address may be
different depending on the bootloader.
In order to have only one central place for the physical address of
the internal registers, we now use of_translate_address() to translate
the mvebu-mbus register offsets into the real physical address, by
using DT-based address translation. This will go away once the
mvebu-mbus driver gains a proper DT binding.

to work with old bootloaders (that keep the internal registers mapped
at 0xd0000000), while the newly introduced option allows to work with
new bootloaders (that remap the internal registers at 0xf1000000).

Subject: [PATCH 033/203] arm: mvebu: fix coherency_late_init() for
multiplatform
As noticed by Arnaud Patard (Rtp) <arnaud.patard@rtp-net.org>, commit
865e0527d2d7 ('arm: mvebu: avoid hardcoded virtual address in
coherency code') added a postcore_initcall() to register the bus
notifier that the mvebu code needs to apply correct DMA operations on
its platform devices breaks the multiplatform boot on other platforms,
because the bus notifier registration is unconditional.
This commit fixes that by registering the bus notifier only if we have
the mvebu coherency unit described in the Device Tree. The conditional
used is exactly the same in which the bus_register_notifier() call was
originally enclosed before 865e0527d2d7 ('arm: mvebu: avoid hardcoded
virtual address in coherency code').

Subject: [PATCH 034/203] ARM: mvebu: fix length of ethernet registers in
mv78260 dtsi
The length of the registers area for the Marvell 370/XP Ethernet controller
was incorrect in the .dtsi: 0x2500, while it should have been 0x4000.
This problem wasn't noticed because there used to be a static mapping for
all the MMIO register region set up by ->map_io().
The register length was fixed in all the other device tree files,
except from the armada-xp-mv78260.dtsi, in the following commit:

Subject: [PATCH 036/203] PCI: mvebu: Disable prefetchable memory support in
PCI-to-PCI bridge
The Marvell PCIe driver uses an emulated PCI-to-PCI bridge to be able
to dynamically set up MBus address decoding windows for PCI I/O and
memory regions depending on the PCI devices enumerated by Linux.
However, this emulated PCI-to-PCI bridge logic makes the Linux PCI
core believe that prefetchable memory regions are supported (because
the registers are read/write), while in fact no adress decoding window
is ever created for such regions. Since the Marvell MBus address
decoding windows do not distinguish memory regions and prefetchable
memory regions, this patch takes a simple approach: change the
PCI-to-PCI bridge emulation to let the Linux PCI core know that we
don't support prefetchable memory regions.
To achieve this, we simply make the prefetchable memory base a
read-only register that always returns 0. Reading/writing all the
other prefetchable memory related registers has no effect.
This problem was originally reported by Finn Hoffmann
<finn@uni-bremen.de>, who couldn't get a RTL8111/8168B PCI NIC working
on the NSA310 Kirkwood platform after updating to 3.11-rc. The problem
was that the PCI-to-PCI bridge emulation was making the Linux PCI core
believe that we support prefetchable memory, so the Linux PCI core was
only filling the prefetchable memory base and limit registers, which
does not lead to a MBus window being created. The below patch has been
confirmed by Finn Hoffmann to fix his problem on Kirkwood, and has
otherwise been successfully tested on the Armada XP GP platform with a
e1000e PCIe NIC and a Marvell SATA PCIe card.

Now that mbus device tree binding has been introduced, remove the address
decoding window management from this driver.
A suitable 'ranges' entry should be added to the devbus-compatible node in
the device tree, as described by the mbus binding documentation.

Subject: [PATCH 046/203] bus: mvebu-mbus: Add new API for the PCIe memory and
IO aperture
We add two optional properties to the MBus DT binding, to encode
the PCIe memory and IO aperture. This allows such information to
be retrieved by -for instance- the pci driver to allocate the
MBus decoding windows.
Correspondingly, and in order to retrieve this information,
we add two new APIs.

Subject: [PATCH 047/203] PCI: mvebu: Adapt to the new device tree layout
The new device tree layout encodes the window's target ID and attribute
in the PCIe controller node's ranges property. This allows to parse
such entries to obtain such information and use the recently introduced
MBus API to create the windows, instead of using the current name based
scheme.

Also, and since the initialization of the mbus driver is quite
fundamental for the system to work properly, this patch adds a BUG()
in case mbus fails to initialize.

From 8298866bfa7fe9c1e33055322c415f612c16a477 Mon Sep 17 00:00:00 2001

Subject: [PATCH 056/203] ARM: mvebu: Add MBus to Armada 370/XP device tree
The Armada 370/XP SoC family has a completely configurable address
space handled by the MBus controller.
This patch introduces the device tree layout of MBus, making the
'soc' node as mbus-compatible.
Since every peripheral/controller is a child of this 'soc' node,
this makes all of them sit behind the mbus, thus describing the
hardware accurately.
A translation entry has been added for the internal-regs mapping.
This can't be done in the common armada-370-xp.dtsi because A370
and AXP have different addressing width.

Subject: [PATCH 057/203] ARM: mvebu: Add BootROM to Armada 370/XP device tree
In order to access the SoC BootROM, we need to declare a mapping
(through a ranges property). The mbus driver will use this property
to allocate a suitable address decoding window.

Subject: [PATCH 058/203] ARM: mvebu: Relocate Armada 370/XP DeviceBus device
tree nodes
Now that mbus has been added to the device tree, it's possible to
move the DeviceBus out of internal registers, placing it directly
below the mbus. This is a more accurate representation of the hardware.

Subject: [PATCH 060/203] ARM: kirkwood: Split DT and legacy MBus
initialization
This commit replaces the legacy MBus initialization with the new
DT-based in Kirkwood. For boards that are not yet converted to DT,
we keep the legacy initialization.

Subject: [PATCH 064/203] ARM: kirkwood: Relocate PCIe device tree nodes
Now that mbus has been added to the device tree, it's possible to
move the PCIe nodes out of the ocp node, placing it directly
below the mbus. This is a more accurate representation of the hardware.
Moving the PCIe nodes, we now need to introduce an extra cell to
encode the window target ID and attribute. Since this depends on
the PCIe port, we split the ranges translation entries, to
correspond to each MBus window.
In addition, we encode the PCIe memory and I/O apertures in the MBus
node, according to the MBus DT binding specification. The choice made
is 0xe0000000-0xf0000000 for memory space, and 0xf200000-0xf2100000 for
I/O space. These apertures can be changed in each per-board DT file.

Subject: [PATCH 065/203] bus: mvebu-mbus: Add devicetree binding
Introduce the devicetree binding for the mvebu MBus driver
avaiable in the mvebu SoCs (Armada 370/XP, Kirkwood, Dove, ...).
This binding provides an accurate model of the SoC address space,
and allows to declare the address and size of the decoding windows the MBus
needs to access the peripherals, together with the target ID and attribute
for those windows.
The binding is composed of two required nodes: one for the MBus bus
and one for the MBus controller.

+ #address-cells = <2>;
+ #size-cells = <1>;
+ controller = <&mbusc>;

+ };
+
+** MBus address decoding window specification
+
+The MBus children address space is comprised of two cells: the first one for
+the window ID and the second one for the offset within the window.
+In order to allow to describe valid and non-valid window entries, the
+following encoding is used:
+
+ 0xSIAA0000 0x00oooooo
+
+Where:
+
+ S = 0x0 for a MBus valid window
+ S = 0xf for a non-valid window (see below)
+
+If S = 0x0, then:
+
+ I = 4-bit window target ID
+ AA = windpw attribute
+
+If S = 0xf, then:
+
+ I = don't care
+ AA = 1 for internal register
+
+Following the above encoding, for each ranges entry for a MBus valid window
+(S = 0x0), an address decoding window is allocated. On the other side,
+entries for translation that do not correspond to valid windows (S = 0xf)
+are skipped.
+
+ soc {
+ compatible = "marvell,armada370-mbus", "simple-bus";
+ #address-cells = <2>;
+ #size-cells = <1>;
+ controller = <&mbusc>;
+
+ ranges = <0xf0010000 0 0 0xd0000000 0x100000
+ 0x01e00000 0 0 0xfff00000 0x100000>;
+
+ bootrom {
+ compatible = "marvell,bootrom";
+ reg = <0x01e00000 0 0x100000>;
+ };
+
+ /* other children */
+ ...
+
+ internal-regs {
+ compatible = "simple-bus";
+ ranges = <0 0xf0010000 0 0x100000>;
+
+ mbusc: mbus-controller@20000 {
+ compatible = "marvell,mbus-controller";
+ reg = <0x20000 0x100>, <0x20180 0x20>;
+ };
+
+ /* more children ...*/
+ };
+ };
+
+In the shown example, the translation entry in the 'ranges' property is what
+makes the MBus driver create a static decoding window for the corresponding
+given child device. Note that the binding does not require child nodes to be
+present. Of course, child nodes are needed to probe the devices.
+
+Since each window is identified by its target ID and attribute ID there's
+a special macro that can be use to simplify the translation entries:
+
+#define MBUS_ID(target,attributes) (((target) << 24) | ((attributes) << 16))
+
+Using this macro, the above example would be:
+
+ soc {
+ compatible = "marvell,armada370-mbus", "simple-bus";
+ #address-cells = <2>;
+ #size-cells = <1>;
+ controller = <&mbusc>;
+
+ ranges = < MBUS_ID(0xf0, 0x01) 0 0 0xd0000000 0x100000
+ MBUS_ID(0x01, 0xe0) 0 0 0xfff00000 0x100000>;
+
+ bootrom {
+ compatible = "marvell,bootrom";
+ reg = <MBUS_ID(0x01, 0xe0) 0 0x100000>;
+ };
+
+ /* other children */
+ ...
+
+ internal-regs {
+ compatible = "simple-bus";

+
+** About the window base address
+
+Remember the MBus controller allows a great deal of flexibility for choosing
+the decoding window base address. When planning the device tree layout it's
+possible to choose any address as the base address, provided of course there's
+a region large enough available, and with the required alignment.
+
+Yet in other words: there's nothing preventing us from setting a base address
+of 0xf0000000, or 0xd0000000 for the NOR device shown above, if such region is
+unused.
+
+** Window allocation policy
+
+The mbus-node ranges property defines a set of mbus windows that are expected
+to be set by the operating system and that are guaranteed to be free of overlaps
+with one another or with the system memory ranges.
+
+Each entry in the property refers to exactly one window. If the operating system
+choses to use a different set of mbus windows, it must ensure that any address
+translations performed from downstream devices are adapted accordingly.
+
+The operating system may insert additional mbus windows that do not conflict
+with the ones listed in the ranges, e.g. for mapping PCIe devices.
+As a special case, the internal register window must be set up by the boot
+loader at the address listed in the ranges property, since access to that region
+is needed to set up the other windows.
+
+** Example
+
+See the example below, where a more complete device tree is shown:
+
+ soc {
+ compatible = "marvell,armadaxp-mbus", "simple-bus";
+ controller = <&mbusc>;
+

Subject: [PATCH 066/203] PCI: mvebu: Adapt to the new device tree layout
The new device tree layout encodes the window's target ID and attribute
in the PCIe controller node's ranges property. This allows to parse
such entries to obtain such information and use the recently introduced
MBus API to create the windows, instead of using the current name based
scheme.

Subject: [PATCH 068/203] ARM: mvebu: use correct #interrupt-cells instead of
#interrupts-cells
The Device Tree information for the GPIO banks of the Armada 370 and
Armada XP SOCs was incorrectly using #interrupts-cells instead of
controller when using GPIO interrupts, since the GPIO bank DT node
wasn't recognized as a valid interrupt controller by the OF code.

Subject: [PATCH 070/203] PCI: use weak functions for MSI arch-specific
functions
Until now, the MSI architecture-specific functions could be overloaded
using a fairly complex set of #define and compile-time
conditionals. In order to prepare for the introduction of the msi_chip
infrastructure, it is desirable to switch all those functions to use
the 'weak' mechanism. This commit converts all the architectures that
were overidding those MSI functions to use the new strategy.
Note that we keep two separate, non-weak, functions
default_teardown_msi_irqs() and default_restore_msi_irqs() for the
default behavior of the arch_teardown_msi_irqs() and
arch_restore_msi_irqs(), as the default behavior is needed by x86 PCI
code.

Subject: [PATCH 071/203] PCI: remove ARCH_SUPPORTS_MSI kconfig option
Now that we have weak versions for each of the PCI MSI architecture
functions, we can actually build the MSI support for all platforms,
regardless of whether they provide or not architecture-specific
versions of those functions. For this reason, the ARCH_SUPPORTS_MSI
hidden kconfig boolean becomes useless, and this patch gets rid of it.

Subject: [PATCH 072/203] PCI: Introduce new MSI chip infrastructure
The new struct msi_chip is used to associated an MSI controller with a
PCI bus. It is automatically handed down from the root to its children
during bus enumeration.
This patch provides default (weak) implementations for the architecture-
specific MSI functions (arch_setup_msi_irq(), arch_teardown_msi_irq()
and arch_msi_check_device()) which check if a PCI device's bus has an
attached MSI chip and forward the call appropriately.

Subject: [PATCH 074/203] irqchip: armada-370-xp: properly request resources
Instead of using of_iomap(), we now use of_address_to_resource(),
request_mem_region() and ioremap(). This allows the corresponding I/O
regions to be properly requested and visible in /proc/iomem.
The main motivation for this change is that the introduction of the
MSI support requires us to get the physical address of the main
interrupt controller registers, so we will need the corresponding
'struct resource' anyway.
We also take this opportunity to change a panic() to BUG_ON(), in
order to be consistent with the rest of the driver.

Subject: [PATCH 075/203] irqchip: armada-370-xp: implement MSI support
This commit introduces the support for the MSI interrupts in the
armada-370-xp interrupt controller driver. It registers an MSI chip to
the MSI chip registry, which will be used by the Marvell PCIe host
controller driver.
The MSI interrupts use the 16 high doorbells, and are therefore
notified using IRQ1 of the main interrupt controller.

Subject: [PATCH 076/203] ARM: pci: add ->add_bus() and ->remove_bus() hooks to
hw_pci
Some PCI drivers may need to adjust the pci_bus structure after it has
been allocated by the Linux PCI core. The PCI core allows
architectures to implement the pcibios_add_bus() and
pcibios_remove_bus() for this purpose. This commit therefore extends
the hw_pci and pci_sys_data structures of the ARM PCI core to allow
PCI drivers to register ->add_bus() and ->remove_bus() in hw_pci,
which will get called when a bus is added or removed from the system.
This will be used for example by the Marvell PCIe driver to connect a
particular PCI bus with its corresponding MSI chip to handle Message
Signaled Interrupts.

Subject: [PATCH 078/203] PCI: mvebu: add support for MSI
This commit adds support for Message Signaled Interrupts in the
Marvell PCIe host controller. The work is very simple: it simply gets
a reference to the msi_chip associated to the PCIe controller thanks
to the msi-parent DT property, and stores this reference in the
pci_bus structure. This is enough to let the Linux PCI core use the
functions of msi_chip to setup and teardown MSIs.

Some Ethernet MACs have a "fixed link", and are not connected to a

binding allows to describe a "fixed link", as a "fixed-link" property
of the Ethernet device Device Tree node.
This patch adds:
* A documentation for the Device Tree property "fixed-link".
* A of_phy_register_fixed_link() OF helper, which provided an OF node
that contains a "fixed-link" property, registers the corresponding
fixed PHY.
* Removes the warning on the of_phy_connect_fixed_link() that says
new drivers should not use it, since Grant Likely indicated that
this "fixed-link" property is indeed the way to go.

+------------------------------

+
+Such a fixed link situation is described within an Ethernet device

Subject: [PATCH 081/203] net: phy: call mdiobus_scan() after adding a fixed
PHY
The fixed_phy_add() function allows to register a fixed PHY. However,
when this function gets called *after* fixed_mdio_bus_init() (which
gets called at the module_init stage), then the fixed PHY is not
registered into the phylib.
In order to address this, we add a call to mdiobus_scan() in
fixed_phy_add() to ensure that the PHY indeed gets registered into the
phylib, even if the fixed_phy_add() is called after
fixed_mdio_bus_init().
This is needed because until now, the only code that was calling the
fixed_add_phy() function was PowerPC-specific platform code, which
could ensure that such fixed PHYs get registered before
fixed_mdio_bus_init() is called.
However, with the new of_phy_register_fixed_link() function, device
drivers can parse their 'fixed-link' property and register a fixed PHY
at ->probe() time, which may happen after fixed_mdio_bus_init() is
called.

clocksource: armada-370-xp: Use CLOCKSOURCE_OF_DECLARE
replaced a call to the driver's timer initialization by a call to
clocksource_of_init(). However, it failed to select CONFIG_CLKSRC_OF.
Fix this by selecting CONFIG_CLKSRC_OF for Armada370/XP machines.
Without this change the kernel is stuck at: 'Calibrating delay loop...'.

Subject: [PATCH 086/203] irqchip: armada-370-xp: fix MSI race condition
In the Armada 370/XP driver, when we receive an IRQ 1, we read the
list of doorbells that caused the interrupt from register
ARMADA_370_XP_IN_DRBEL_CAUSE_OFFS. This gives the list of MSIs that
were generated. However, instead of acknowledging only the MSIs that
were generated, we acknowledge *all* the MSIs, by writing
~MSI_DOORBELL_MASK in the ARMADA_370_XP_IN_DRBEL_CAUSE_OFFS register.
This creates a race condition: if a new MSI that isn't part of the
ones read into the temporary "msimask" variable is fired before we
acknowledge all MSIs, then we will simply loose it.
It is important to mention that this ARMADA_370_XP_IN_DRBEL_CAUSE_OFFS
register has the following behavior: "A CPU write of 0 clears the bits
in this field. A CPU write of 1 has no effect". This is what allows us
to simply write ~msimask to acknoledge the handled MSIs.
Notice that the same problem is present in the IPI implementation, but
it is fixed as a separate patch, so that this IPI fix can be pushed to
older stable versions as appropriate (all the way to 3.8), while the
MSI code only appeared in 3.13.

Subject: [PATCH 088/203] ARM: mvebu: re-enable PCIe on Armada 370 DB
Commit 14fd8ed0a7fd19913 ("ARM: mvebu: Relocate Armada 370/XP PCIe
device tree nodes") relocated the PCIe controller DT nodes one level
up in the Device Tree, to reflect a more correct representation of the
hardware introduced by the mvebu-mbus Device Tree binding.
However, while most of the boards were properly adjusted accordingly,
the Armada 370 DB board was left unchanged, and therefore, PCIe is
seen as not enabled on this board. This patch fixes that by moving the
PCIe controller node one level-up in armada-370-db.dts.

Subject: [PATCH 090/203] mtd: add datasheet's ECC information to nand_chip{}
1.) Why add the ECC information to the nand_chip{} ?
Each nand chip has its requirement for the ECC correctability, such as
"4bit ECC for each 512Byte" or "40bit ECC for each 1024Byte".
This ECC info is very important to the nand controller, such as gpmi.
Take the Micron MT29F64G08CBABA for example, its geometry is
8KiB page size, 744 bytes oob size and it requires 40bit ECC per 1KiB.
If we do not provide the ECC info to the gpmi nand driver, it has to
calculate the ECC correctability itself. The gpmi driver will gets the 56bit
ECC for per 1KiB which is beyond its BCH's 40bit ecc capibility.
The gpmi will quits in this case. But in actually, the gpmi can supports
this nand chip if it can get the right ECC info.
2.) about the new fields.
The @ecc_strength_ds stands for the ecc bits needed within the @ecc_step_ds.
The two fields should be set from the nand chip's datasheets.
For example:
"4bit ECC for each 512Byte" could be:
@ecc_strength_ds = 4, @ecc_step_ds = 512.
"40bit ECC for each 1024Byte" could be:
@ecc_strength_ds = 40, @ecc_step_ds = 1024.
3.) Why do not re-use the @strength and @size in the nand_ecc_ctrl{}?
The @strength and @size in nand_ecc_ctrl{} is used by the nand controller
driver, while the @ecc_strength_ds and @ecc_step_ds are get from the datasheet.

Subject: [PATCH 091/203] mtd: add data structures for Extended Parameter Page
Since the ONFI 2.1, the onfi spec adds the Extended Parameter Page
to store the ECC info.
The onfi spec tells us that if the nand chip's recommended ECC codeword
size is not 512 bytes, then the @ecc_bits is 0xff. The host _SHOULD_ then
read the Extended ECC information that is part of the extended parameter
page to retrieve the ECC requirements for this device.
This patch adds
[1] the neccessary fields for nand_onfi_params{},
[2] and adds the onfi_ext_ecc_info{} for Extended ECC information,
[3] adds onfi_ext_section{} for extended sections,
[4] and adds onfi_ext_param_page{} for the Extended Parameter Page.

Subject: [PATCH 095/203] mtd: nand: fix memory leak in ONFI extended parameter
page
This fixes a memory leak in the ONFI support code for detecting the
required ECC levels from this commit:
commit 6dcbe0cdd83fb5f77be4f44c9e06c535281c375a
Author: Huang Shijie <b32955@freescale.com>
Date: Wed May 22 10:28:27 2013 +0800
mtd: get the ECC info from the Extended Parameter Page
In the success case, we never freed the 'ep' buffer.
Also, this fixes an oversight in the same commit where we (harmlessly)
freed the NULL pointer.

Subject: [PATCH 096/203] clk: mvebu: Add Core Divider clock
This commit introduces a new group of clocks present in Armada 370/XP
SoCs (called "Core Divider" clocks) and add a provider for them.
The only clock supported for now is the NAND clock (ndclk), but the
infrastructure to add the rest is already set.

Subject: [PATCH 100/203] ARM: mvebu: Enable NAND controller in Armada XP GP
board
The Armada XP GP board has a NAND flash, so enable it in the devicetree.
In order to skip the driver's custom device detection and use only ONFI
detection, the "marvell,keep-config" parameter is used.
This is needed because we haven't support for setting the timings
parameters yet and must rely in bootloader's.

Subject: [PATCH 106/203] mtd: nand: pxa3xx: Move buffer release code to its
own function
Create a function to release the buffer and the dma channel, thus undoing
what pxa3xx_nand_init_buff() did. This commit makes the code more readable
and will allow to handle non-DMA capable platforms easier.
