Not sure since when the issue emerged, but according to the current doc of gcc
and as, armv8-a is intended as argument of -march
The change will affect at the moment arm64 and layerscape/64b
Below is the relevant error messages when building toolchain
Assembler messages:
Error: unknown cpu `armv8-a'
Error: unrecognized option -mcpu=armv8-a

If someone creates a target and indicates a CPU_TYPE, but there's
no corresponding support for that CPU_TYPE's flags in include/target.mk
then that should probably be indicated rather than silently ignored.

This can be used to indicate that a target does not support the optional mips16
extension even when it is a mips32r2 or later CPU.
This will generate a separate toolchain and a separate package folder,
e.g. mips_24kc_nomips16

-mXXX option is deprecated already in arc-2016.03 toolchain
and removed completely starting from arc-2016.09.
Direct replacement is -mcpu=XXX which is already supported by
arc-2016.03 used today in Lede.
With that change we'll be ready for ARC toolchain update still
keeping everything working with current tools.

According to some reports, -march=pentium-mmx is a better choice for
older Geode CPUs than -march=geode anyway.
Bump the minimum architecture of the legacy target from i486 to
pentium-mmx. Anything older is not worth supporting anyway.

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.

9pfs is used by kvm to share files between host and guest,

Since the only difference between 24Kec and 24Kc is the addition of DSP
ASE support, and we don't use it anymore, there is no need to keep 24Kec
as a separate cpu type.

There does not seem to be any meaningful difference in generated code.
This will save some time and space on snapshot builds

-march forces the compiler to generate generic code, whereas -mcpu
allows it to target the specific CPU variant and use instructions that
the generic architecture may not have

Use kernel config as input instead of -march CFLAGS.
With this change, -march can be dropped and replaced with more specific
optimization flags for better code generation.

Add $ARCH and $CPU_SUBTYPE to the package architecture strings to differentiate
low and big endian targets as well as extended instructions sets like NEON
or DSP2.
Signed-off-by: Jo-Philipp Wich <jo@mein.io>
Use the more specific CPU_TYPE designation as default package architecture
and only fall back to ARCH if no specific CPU_TYPE is set.
This means that e.g. ar71xx packages will use "74kc" as architecture,
not "mips" which is a precondition for sharing packages between targets.

This patch introduces support of new boards with ARC HS38 cores.
ARC HS38 is a new generation of ARC cores which utilize ARCv2 ISA.
As with ARC770 we're addind support for 2 boards for now:
[1] Synopsys SDP board (AXS103)
This is the same base-board as in AXS101 but with
FPGA-based CPU-tile where ARCHs38 core is implemented.
[2] nSIM
Again this is the same simulation engine but configured for
new instruction set and features of new CPU.

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.

This includes binutils, gcc, gdb and uClibc-ng.
Latest release of ARC gcc (as of today it is "arc-2015.06")
is based on upstream gcc 4.8.4.
Sources are available on GitHub, see:
https://github.com/foss-for-synopsys-dwc-arc-processors/gcc
Latest release of ARC binutils (as of today it is "arc-2015.06")
is based on upstream binutils 2.23.
Sources are available on GitHub, see:
https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/releases/tag/arc-2015.06
Latest release of ARC GDB (as of today this is "arc-2015.06-gdb")
is based on upstream gdb 7.9.1.
Sources are available on GitHub, see:
https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/releases/tag/arc-2015.06-gdb
Note that for binutils and gdb that come from unified git repository
(which is the case for upstream binutils/gdb today) we need to disable
building of gdb in binutils and binutils in gdb hence in binutils:
------>8------
--disable-sim
--disable-gdb
------>8------
and in gdb:
------>8------
--disable-binutils
--disable-ld
--disable-gas
------>8------
Also in gdb we disable sim because if the following breakage while
building with it:
------------>8------------
/usr/bin/env bash ./../common/genmloop.sh -shell /usr/bin/env bash \
-mono -fast -pbb -switch sem5-switch.c \
