Hans Dedecker 8b9cdebc9c arc770: mark as source-only
Mark target arc770 as source-only as it has package compile issues
(e.g. iproute2) due to the usage of uClibc.
As a prerequisite to be included in future releases the arc770 target
needs to switch either to glibc or musl.

Alexey Brodkin aab344d227 arc770: backport upstream fix for unaligned access
This commit reverts 42f3c1f ("arc770: fix broken upstream change")
and simultaneously adds back-ported fix from Linus' tree:
a524c218bc94 ("ARC: [arcompact] brown paper bag bug in unaligned
access delay slot fixup").

Note mentioned patch will appear in stable trees soon as well so
IMHO there's not much sense in adding this separate patch in lede/master branch.
As well as we will get rid of it here in 17.01 once we bump 4.4 kernel here
later down the line.

Alexey Brodkin 30d75720fa arc770: Introduce images for SD-cards
Historically on ARC we started from initramfs-based images because:
 a) It was much easier to debug especially when toolchain and other
    components were changing quite dynamically
 b) It was our usual approach for embedded Linux

But now with ARC port of Lede/OpenWRT getting more stable and mature
we're ready for more real-life scenarios with FS permanently stored
on SD-card. This essentially benefits from ability to setup devices
that survive reboots with all settings and extra packages kept in place.

Still we keep an ability to build images with initramfs.
This allows us to use storage-less simulators for testing still.

Alexey Brodkin cf3364a363 arc770: Update kernel configuration
Now when we're switching to FS on SD-card it's necessary to have
full stack of MMC block & FC drivers built-in otherwise kernel won't
be able to mount FS with needed modules.

Also we enable parsing of input parameters passed to the kernel by
U-Boot. Otherwise kernel won't know where to look for command line and
what's worse device tree blob (we had to disable this by default for
cases when kernel is loaded by JTAG and core registers may have
undefined state lading to kernel going bonkers).

Alexey Brodkin 07e653725a arc770: Reduce generalization
As support of ARC 770 in OpenWRT/Lede matures we don't need
debug-only output binaries any longer, so purging vmlinux for
AXS10x boards.

As for uImage for nSIM it makes completely no sense because there's no
way to run U-Boot on nSIM.

So we remove add_arcYYY_XXX scripts making code more compact and
cleaner.

Alexey Brodkin 66f3edfd8b linux/arc*: disable MAC frame filter in DW GMAC
DW GMAC on ARC SDP boards doesn't enter promiscuous mode if
Ethernet PHY haven't got established link. Good examples are
auto-negotiation in progress or disconnected cable.

We do see Linux kernel sets GMAC's MAC filter register
properly but GMAC's hardware doesn't accept new settings.

We believe it is a hardware issue, most probably problem of
integration of DW GMAC and PHY on the board.

As a work-around we completely disable frame filtering
in GMAC hardware (once and for good) which forces GMAC to enter
promiscuous mode with the first write to MAC filter register.
That gives us working bridge that consists of eth0 and wlan0
(USB Wi-Fi dongle). I.e. we finally have working "Dumb AP" setup made
of ARC AXS10x boards.

Given that hack is quite dirty (in loaded wired networks this will
effectively load CPU with junk packets even if user doesn't need promisc
mode) and there's no indication any other boards with DW GMAC suffer
from the same issue we're patching only kernel for ARC boards.

Alexey Brodkin acd41539d6 linux: arc: disable kernel unwinding to fix modules loading
With update of binutils for ARC (this is now based on upstream 2.26)
we noticed issues with loadable kernel modules.

Something like that was happening:
--------------------->8-------------------
mbcache: unknown relocation: 49
insmod: can't insert './mbcache.ko': invalid module format
--------------------->8-------------------

More details could be found in that discussion in binutils mailing list:
http://thread.gmane.org/gmane.comp.gnu.binutils/74662

As of now the simplest work-around is to disable in-kernel unwinder
for now. That will at least allow us to use modules again.

Alexey Brodkin 668dbec3f4 arc: Build uImage as well as vmlinux output files
Initially for ARC we were building vmlinux images because it
was both simpler and more convenient to debug Linux kernel
in runt-time via JTAG. Now when base system works quite nice
we may finally use U-Boot for loading the system image as
well. Still we keep building vmlinux images as some of our
boards are development boards and loading images with JTAG
could be at some points very beneficial.

Note for U-Boot header it's required to specify 2 values:
 * loading address
 * entry point (if it doesn't match loading address)

and in case of ARC entry point (EP) not only differs from
loading address but also changes from build to build due to
initramfs being placed between loading address and text section.
To accommodate that feature we have to calculate EP after
vmlinux gets built and before call to mkimage.

John Crispin 9ef282cd96 arc770: enable unaligned access handling simulation in software
This enables misaligned access handling by software in Linux kernel.

With some wireless drivers (ath9k-htc and mt7601u for example) we see
misaligned accesses here and there and to cope with that without

Most of currently mentioned CFLAGS in arc770/Makefile
are not really required because:
 [1] "-Os -pipe" are set by default in include/target.mk
 [2] "-fno-caller-saves" gets enabled via menuconfig

So the only one that makes sense is "-matomic" and
that one is really essential. Without it many software
packges won't build complainin on unresolved atomic ops.

Felix Fietkau 018e84f58d arc770/axs101: fix console output
While bumping kernel version kernel command line was
unintentionally modified in attempt to make it closer
to upstream version.

In case of AXS that has not only serial port but HDMI/USB
both capable of being debug console we have 2 entries in
kernel's command line:
------------------->8-----------------
console=tty0 console=ttyS3,115200n8
------------------->8-----------------

But as it turned out OpenWRT uses procd as init instead of
Busybox. And in its turn procd gets the first "console"
entry from kernel command line (/proc/cmdline) and uses it
if default inittab is used:
------------------->8-----------------
...
::askconsole:/bin/ash --login
------------------->8-----------------

So what we got is non-functional serial console.
That change removes "console=tty0" which brings serial
console back to life.

Felix Fietkau 576621f1e3 linux: add support of Synopsys ARC770-based boards
This patch introduces support of new boards with ARC cores.

 [1] Synopsys SDP board
     This is a new-generation development board from Synopsys that
     consists of base-board and CPU tile-board (which might have a real
     ASIC or FPGA with CPU image).
     It sports a lot of DesignWare peripherals like GMAC, USB, SPI, I2C
     etc and is intended to be used for early development of ARC-based
     products.

 [2] nSIM
     This is a virtual board implemented in Synopsys proprietary
     software simulator (even though available for free for open source
     community). This board has only serial port as a peripheral and so
     it is meant to be used for runtime testing which is especially
     useful during bring-up of new tools and platforms.
     What's also important ARC cores are very configurable so there're
     many variations of options like cache sizes, their line lengths,
     additional hardware blocks like multipliers, dividers etc. And this
     board could be used to make sure built software still runs on
     different HW configurations.
