85b1f4d8ca treewide: remove execute bit and shebang from board.d files
So far, board.d files were having execute bit set and contained a
shebang. However, they are just sourced in board_detect, with an
apparantly unnecessary check for execute permission beforehand.

Replace this check by one for existance and make the board.d files
"normal" files, as would be expected in /etc anyway.

Note:

This removes an apparantly unused '#!/bin/sh /etc/rc.common' in
target/linux/bcm47xx/base-files/etc/board.d/01_network

cc501ab021 kernel: set WATCHDOG_CORE dependency in kmod-hwmon-sch5627
For many target we have added CONFIG_WATCHDOG_CORE=y to the target
config due to the following error:

 Package kmod-hwmon-sch5627 is missing dependencies for the following
 libraries:
 watchdog.ko

However, actually the proper way appears to be setting the
dependency for the kmod-hwmon-sch5627 package, as the error message
demands.

Do this in this patch and remove the target config entries added
due to this issue.

bcd7a0c095 arc770: update kernel version to 5.4
Update config with make kernel_oldconfig and copy/refresh patch.

Add CONFIG_WATCHDOG_CORE=y to fix the following error as done for
several targets already:

 Package kmod-hwmon-sch5627 is missing dependencies for the following
 libraries:
 watchdog.ko

Directly switch to kernel 5.4.

This patch is compile-tested only. However, the target is essentially
pure upstream with a single patch, and it has been reported that
kernel 5.4 has been run on this target successfully already.

Note that in my local tests building with all packages/kmods failed
since openvswitch selects libunwind, which doesn't build for arc with
the following error:

checking if we should build libunwind-ptrace... yes
checking if we should build libunwind-setjmp... yes

0a5d74fa68 arc770: use generic 02_sysinfo
Currently arc770 sets a board name from compatible for no apparent
reason. Just use the compatible directly instead.

This theoretically removes a board name "generic" when no compatible
was present, however, there is no case where this "generic" board
name was actually used.

This also fixes an issue where snps,axs101 would not have been
properly detected anyway, as its case was not set up syntactically
correct.

057e5f6ede treewide: provide consistent basic DEVICE_TYPE
While the effective "default" based on frequent use is "router", the
DEVICE_TYPE variable actually provides a "basic" configuration without
selecting any additional packages.

This is currently set up with the identifier "bootloader", which seems
to be not used at all. However, the only targets not using "router" or
"nas" are actually archs38 and arc770, which use their own value
"developerboard" for DEVICE_TYPE which seems to have been invented when
these targets where added. The latter is not implemented in target.mk,
though, and will fall back to the "basic" set of packages then.

So, to clean this up and make it more readable, let's just define a
DEVICE_TYPE "basic" and use it for the aforementioned cases.

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.

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.

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.

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.

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
fixing stuff in the drivers we're just gracefully handling it on ARC.

cac43c0b71 arc770: build kmod-ath9k-htc wpad-mini by default
AXS101 beind a development board lacks built-in wireles inerfaces.
So we have to use external USB dongles to turn the board into
wireless router.

The best USB Wi-Fi dongles to work in AP-mode seem to be based on
ath9k-htc chipset.

And so with that change we add support of mentioned dongles in
default and axs101 builds.

e620f4d6f8 arc: clean-up and move CFLAGS to include/target.mk
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
     as an extra compiler flag for developers

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.
