elf2flt does not support ARM big-endian, so supporting Cortex M3/M4/M7
with armeb is not possibly.
Therefore this commit makes:
- MMU mandatory on armeb
- Prevents from seeing Cortex M3/M4/M7 on armeb

So far, all ARM cores were selecting BR2_ARCH_HAS_MMU_OPTIONAL, except
no-MMU cores which were selecting nothing.
In practice, MMU-capable ARM cores are always used with their MMU
enabled, so it doesn't make sense to support the use case of not using
the MMU on such cores.
Consequently, to simplify things, we group the MMU handling in the
BR2_ARM_CPU_ARM* options: BR2_ARM_CPU_ARMV4, BR2_ARM_CPU_ARMV5,
BR2_ARM_CPU_ARMV6, BR2_ARM_CPU_ARMV7A, BR2_ARM_CPU_ARMV8A all select
BR2_ARCH_HAS_MMU_MANDATORY, while BR2_ARM_CPU_ARMV7M continues to
select nothing, indicating that there is no MMU available at all.

The variable 'KERNEL_ARCH' is actually a normalized version of
'ARCH'/'BR2_ARCH'. For example, 'arcle' and 'arceb' both become 'arc', just
as all powerpc variants become 'powerpc'.
It is presumably called 'KERNEL_ARCH' because the Linux kernel is typically
the first place where support for a new architecture is added, and thus is
the entity that defines the normalized name.
However, the term 'KERNEL_ARCH' can also be interpreted as 'the architecture
used by the kernel', which need not be exactly the same as 'the normalized
name for a certain arch'. In particular, for cases where a 64-bit
architecture is running a 64-bit kernel but 32-bit userspace. Examples
include:
* aarch64 architecture, with aarch64 kernel and 32-bit (ARM) userspace
* x86_64 architecture, with x86_64 kernel and 32-bit (i386) userspace
In such cases, the 'architecture used by the kernel' needs to refer to the
64-bit name (aarch64, x86_64), whereas all userspace applications need to
refer the, potentially normalized, 32-bit name.
This means that there need to be two different variables:
KERNEL_ARCH: the architecture used by the kernel
NORMALIZED_ARCH: the normalized name for the current userspace architecture
At this moment, both will actually have the same content. But a subsequent
patch will add basic support for situations described above, in which
KERNEL_ARCH may become overwritten to the 64-bit architecture, while
NORMALIZED_ARCH needs to remain the same (32-bit) case.
This commit replaces use of KERNEL_ARCH where actually the userspace arch is
needed. Places that use KERNEL_ARCH in combination with building of kernel
modules are not touched.
There may be cases where a package builds both a kernel module as userspace,
in which case it may need to know about both KERNEL_ARCH and
NORMALIZED_ARCH, for the case where they differ. But this is to be fixed on
a per-need basis.

In gcc-9, some cores from the ThunderX familly have been renamed to
their marketting names, i.e. OcteonTX. Subsequently, new core names
have been added to gcc, with the old names still being around.
Update the prompts with the new names as alternative to the existing
names. We still keep the kconfig options as-is, so that we do not need
to add legacy handling.
However, since there is no guarantee for how long gcc will retain
compatibility for the older names, we readily switch over to using the
new names when using a gcc 9-or-later, but keep using the older names
with gcc older than 9.

The armv8.2a generation is a cumulative extension to armv8.1a.
Since gcc correctly enables the appropriate extensions based on the core
name, we don't really need to introduce a separate config for armv8.2a,
and we can piggyback on armv8a.
In theory, gcc supports those cores in arm mode. However, configuring
gcc thusly generates a non-working gcc that constantly whines:
cc1: warning: switch -mcpu=cortex-a55 conflicts with -march=armv8.2-a switch
It is to be noted that the -march flag is internal to gcc. It is not
something that Buildroot did set when configuring gcc; Buildroot only
ever sets --with-cpu (not --with-arch).
Additionally, uClibc fails to build entirely (unsure if this is caused
by the above, or if it is a separate issue, though), with:
#### Your compiler does not support TLS and you are trying to build uClibc-ng
#### with NPTL support. Upgrade your binutils and gcc to versions which
#### support TLS for your architecture. Do not contact uClibc-ng maintainers
#### about this problem.
Glibc and musl have not been tested in arm mode, so maybe we could have
a toolchain that eventually works (or at least, pretends to be working),
but we decided it was not worth the effort.
Thus, we restrict those cores to AArch64 mode only.

Currently, we consider that any VFP FPU is a superset of VFPv2, and thus
we use VFPv2 as a way to detect that a VFP is used.
However, for Cortex-M cores, the optional FPU is not a superset of
VFPv2; it is even not a VFP [0].
As a consequence, we can no longer consider VFPv2 as a indication that
an FPU is present.
So, we introduce two new internal options, BR2_ARM_CPU_MAYBE_HAS_FPU and
BR2_ARM_CPU_HAS_FPU, which we use to consider the presence of an FPU.

It's been a while now that we do not support OABI, but the dependency
stuck all along.
Remove it as it is no longer needed, and is always true.
However, the choice is empty for AArch64, as we still have no entry for

The 64 bits ARM processors are capable of running 32 bits ARM code, and
some platforms are indeed using this capability. Due to this, if we were
to keep the separation between Config.in.aarch64 and Config.in.arm, we
would have to duplicate the definition of all 64-bits capable ARM cores
into both files.
Instead of going down this route, let's take the same route as the x86
one: a single Config.in.x86 file, used for both x86 32 bits and x86 64
bits, with the appropriate logic to only show the relevant cores
depending on which architecture is selected.
In order to do this, we:
- Make the "ARM instruction set" choice only visible on ARM 32 bits,
since we currently don't support ARM vs. Thumb on AArch64.
- Add the relevant values for the BR2_ARCH option.
- Add the relevant values for the BR2_ENDIAN option.
- Make the "aapcs-linux" BR2_GCC_TARGET_ABI value only used on ARM 32
bits, since this ABI doesn't mean anything on AArch64.
- Make the BR2_GCC_TARGET_FPU option depends on ARM 32 bits, since
there is no -mfpu option on AArch64.
