MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Broadcom ARM devices seem to generate some fault once per boot. We
already have an ignoring handler for BCM4707/BCM4708, but BCM4709
generates different code.

The driver for the PCIe controller was just added, this adds the
missing definition of the IRQ numbers to device tree. The driver itself
will be automatically detected by bcma.

Subject: [PATCH 03/17] bcm47xx-sprom: add Broadcom sprom parser driver
This driver needs an nvram driver and fetches the sprom values from the
nvram and provides it to any other driver. The calibration data for the
wifi chip the mac address and some more board description data is
stores in the sprom.
This is based on a copy of arch/mips/bcm47xx/sprom.c and my plan is to
make the bcm47xx MIPS SoCs also use this driver some time later.

From cf067bf8bb993d6cfdc42d750ae241c43f88403f Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/2] PCI: BCM5301X: add PCIe2 driver for BCM5301X SoCs
This driver supports the PCIe controller found on the BCM4708 and
similar SoCs. The controller itself is automatically detected by bcma.
This controller is found on SoCs usually used in SOHO routers to
connect the wifi cards to the SoC. All the of the BCM5301X SoCs I know
of have 2 or 3 of these controllers in the SoC.
I had to use PCI domains otherwise the pci_create_root_bus() function
in drivers/pci/probe.c would fail for the second controller being
registered because pci_find_bus() would find the same PCIe bus again
and assume it is already registered, which ends up in a kernel panic in
pcibios_init_hw() in arch/arm/kernel/bios32.c
The ARM PCI code assumes that every controller has an I/O space and
adds a dummy area if the driver does not specify one. This will work
for the first controller, but when we register the second one this will
result in an error. To prevent this problem we add an empty I/O space.
Currently I have problems with probing the devices on the bus, because
pci_bus_add_devices() is called too early in pci_scan_root_bus() in
drivers/pci/probe.c, before pci_bus_assign_resources() was called in
pci_common_init_dev() in arch/arm/kernel/bios32.c. When the devices are
added too early they do not have any resources and adding fails. I have
to remove the call to pci_bus_add_devices() in pci_scan_root_bus() to
make registration work, calling pci_bus_add_devices() later again does
not fix this problem.

Subject: [PATCH] USB: bcma: remove chip id check
I have never seen any bcma device with an USB host core which was not a
SoC, the bcma devices have an USB device core with a different core id.
Some SoC have IDs with 47XX and 53XX in decimal form which would be
rejected by this check. Instead of fixing this check just remove it.

In OpenWrt we still use old NAND driver instead of "brcm,nandcs", so
we need to add this DT entry back.

So far we were supporting up to 2 cores but recent devices (e.g. Netgear

some offloading then.

Subject: [PATCH RFC] bcma: use two different initcalls if built-in
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This is needed as we can't initialize bus during fs_initcall.
Initialization requires SPROM which depends on NVRAM which depends on
mtd. Since mtd, spi, nand, spi-nor use standard module_init, we have to
do the same in bcma.
Without this we'll try to initialize SPROM without having a ready SPROM
proviver registered using bcma_arch_register_fallback_sprom.
Signed-off-by: Rafał Miłecki <zajec5@gmail.com>

While this patch seems to work and I can compile bcma as built-in and
module, I'm not too proud of it. I don't really like these #if(n)def
tricks and I'm afraid bcma_modinit may be called even if
bcma_modinit_early failed.
Do you see any better idea of solving this?

It wasn't working (on most of devices?) without setting GPIO direction
and wasn't respecting ACTIVE_LOW flag.
