commit 3613b2780a6b5d5d70ea6802be5060a8214cbdb5 from
git://github.com/renesas-rcar/meta-renesas
The renesas rcar SoC H3/M3 is big.LITTLE architecture(cortex-a57.cortex-a53).
In order to optimize the performance of the code running on SoC H3/M3,
add a tune file for ARM Cortex-A53-Cortex-A57.
Create this tune file by refering GCC doc, 3.18.5 ARM Options.

Since TUNE_FEATURES now either contains a CPU or an architecture (but
not both) we can't rely on finding the architecture in TUNE_FEATURES.
Use architecture specific over-rides instead.

There was a discussion about what amount of RAM is appropriate for a
default; the outcome was that for now it is still 256M. Some qemu machine
definitions have however set this to 512M so for the sake of
treating all architectures fairly, they are reset back to 256M.
Also runqemu is adjusted to use 256M if QB_MEM is not set at all.

tune files which inherit the arch definitions already define appropriate
-mcpu option, which is equivalent of right -march and -mtune combination
and is preferred since gcc is getting stricter and stricter with option
check semantics and can now find incompatible -march and -mcpu options
better with every release. It does internal feature consistency check
and if it finds out discrepency between what -mcpu would expand to as
compared to -march it will flag the options to be incompatible, for
naked eye it sounds wrong but gcc would translate -mcpu to a given
-march internally and it might not match to what we set in these arch
files.
The effects are quite subtle, where this can result in configure test
failing to compile due to these incompatible options and a feature
option getting disabled for a recipe for no reason.
e.g. with gcc9 which can now detect that -mcpu=cortex-a5 and
-march=armv7-a are incompatible, many features in libstdc++ ends up
disabled due to configure check failures e.g. size_t size, ptrdiff_t
sizes, which inturn results in compiling libstdc++ with unwanted
disabled features.

-march=armv5't'e means that CPU can execute thumb ISA, we do not need to
tie this to exclusively generating thumb ISA, this change means that
when we have thumb in tune features then it can use 't' in -march
options irrespective of ISA being thumb or arm.
This fixes derivative of armv5 tunes and paves way for gcc9 where e.g.
armv5e is dropped and minimum arch supported is armv5te

Historically first PowerPC ABI was big-endian only (elfv1 currently). It
is standard ABI for both 32-bit ppc and 64-bit ppc64 architectures.
With PowerPC little-endian support new ABI was introduced (elfv2) and it
is used primarily with ppc64le target only. While it has support for
big-endian it is not commonly used and elfv1 still preferred.
Musl does support only elfv2 ABI for both LE and BE and does not have
any plans to support elfv1.
Since then to build for powerpc64 with musl new ABI should be used. As
expected it is not compatible with elfv1 but that isn't problem as long
as there is no binary distributed software or assembly code written for
elfv1 ABI.
