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.

If we want to boot from SD-card we need to have corresponding
drivers already built-in so there's no point in having these
modules.

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).

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.

This tool can periodically check for ath10k firmware crashes.
If it finds a crash, it will package up the binary crash dump,
some OS level things like dmesg, lspci, etc into a tar file.
It then notifies the user about the crash and asks them to report
the bug to the appropriate email address.
This is most useful when used with ath10k-ct driver and
CT ath10k firmware, but it should also report issues with stock
ath10k driver and firmware in case one has appropriate contacts
to debug them.
This tool could be extended later for other modules/bugs/etc.

Drivers have been modified to use it and new ones have to be written
this way, so we need it for backporting code.

The iwinfo library might get compiled with different backends, depending on
the driver selection of the current target, so mark it as nonshared to avoid
broken libiwinfo support on other targets with same cpu architecture but
different wireless driver types.

With 12fe4b5798 I switched the ath5k
eeprom extraction to an alternate code path. Unfortunately this code
seams to be broken since ages and broke the ath5k EEPROM extraction.

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.

1004kc is just a SMP capable 34kc, and GCC treats 24kc and 34kc exactly
the same and will generate identical code, so there is no need to tune
to 1004kc instead of 24kc.
