The condition to indicate whether there is a runtime devicetree available

vexpress_ca9x4 is seemingly the only board except for qemu_arm which
is able to run U-Boot correctly, using the `-M vexpress-a9` option to
QEMU. Building for qemu_arm and running qemu-system-arm with the `-M
virt` argument has a number of downsides, most importantly that it
only supports virtio storage drivers. This significantly reduces its
usefulness in testing memory card and Flash solutions, especially when
the tested images are from a third party source.
So therefore we reintroduce the vexpress_ca9x4 board in this commit,
with the explicit goal of using it with QEMU.
A number of differences to note from the original:
* Since the board was apparently unmaintained, I have now set myself
as the maintainer.
* The board has been converted to use the driver model, which was the
reason it was removed in the first place.
* The vexpress_ca15_tc2 and vexpress_ca5x2 boards, which were removed
in the same commit, are not necessary for the QEMU use case, and
have been omitted.
* An `mmc0` alias was introduced in the dts file. The mmc is not
detected correctly without this, now that it's based on the device
tree instead of the board's init function.
* A couple of other nodes were removed because they were problematic
when trying to run the UEFI bootmgr. Once again, the primary use
case here is QEMU, and these nodes are not needed for that to work.
* Unnecessary board init code has been removed, thanks to driver model
and device tree.
* `CONFIG_OF_EMBED` has been enabled. I know this goes against
recommended practice, but there doesn't seem to be any other way to
pass the dtb to U-Boot in the QEMU scenario. Using the -dtb argument
does not work, I suppose because U-Boot doesn't use the same
mechanics as the kernel when it's booting.
* Load addresses have been changed to fit QEMU use case.
People wanting to get a more detailed, yet somewhat isolated, diff
between this and the original, can run this command:

Note that memmove is also handled by the memcpy function.
Please note that when adding these optimized functions as default memset
memcpy functions in U-Boot, U-Boot fails to boot on the LX2160ARDB.
After the initial ATF output, no U-Boot output is shown on the serial
console. Some exception is triggered here in the very early boot process
as some of the assembler opcodes need the caches to be enabled.
Because of this, a follow-up patch will add a check to use a simple
non-optimized memset for the "cache disabled" case.
Note:
I also integrated and tested with the Linux versions of these optimized
functions. They are similar to the ones now integrated but these ARM
versions are still a small bit faster.

Lower 4 bits of PCI_IO_BASE and PCI_IO_LIMIT register contain information

On MediaTek boards we cannot override the SYS_BOARD / SYS_CONFIG_NAME

This is because in board/mediatek/mtXXXX/Kconfig this value was override

This function is clearly architecture specific code, not board specific
code. The only difference from the previous arm arch_lmb_reserve() is the
extra reservation of 16k of memory below the stack bottom, rather than
the 4k. The common code now also uses 16k alignment. Remove this custom
implementation, as it now behaves exactly as the common code.

According to input NXP, the 4k alignment is not always sufficient.
Currently iMX works around this problem by implementing board specific
LMB reservation, however it is likely this could also occur on other
systems. Increase the LMB reservation alignment to 16k by default.

The arc/arm/m68k/microblaze/mips/ppc arch_lmb_reserve() implementations
are all mostly the same, except for a couple of details. Implement a
generic arch_lmb_reserve_generic() function which can be parametrized
enough to cater for those differences between architectures. This can
also be parametrized enough so it can handle cases where U-Boot is not
relocated to the end of DRAM e.g. because there is some other reserved
memory past U-Boot (e.g. unmovable firmware for coprocessor), it is not
relocated at all, and other such use cases.

ARMv8.0 has optional crc32 instruction for crc32 calculation. The
instruction is mandatory since ARMv8.1. The crc32 calculation is
faster using the dedicated instruction, e.g. 1.4 GHz iMX8MN gives:
=> time crc32 0x50000000 0x2000000
time: 0.126 seconds # crc32 instruction
time: 0.213 seconds # software crc32

Avoid applying the "fix" introduced by commit 5557eec01c ("env: Fix
invalid env handling in env_init()") to the environment "nowhere".
This is necessary as that commit, by setting the return value of
env_init() to -ENOENT if gd->env_valid is ENV_INVALID, forces that
function to reset gd->env_valid to ENV_VALID. By doing so, it breaks the
assumption (required by ENV_IS_NOWHERE) that gd->env_valid must be
ENV_INVALID.
This, in turn, results in env_relocate() calling env_load() (it should
not), which itself, calls U_BOOT_ENV_LOCATION(nowhere).load() i.e.
env_nowhere_load(). That function, being implemented under the
assumption mentioned above, calls env_set_default(), which in turn,
seeing that gd->env_valid is ENV_VALID (it should not), tries to
dereference whatever lies in gd->env_addr (most likely garbage), leading
to a faulty memory access.
Note that other env_locations might be concerned by this bug but that
this commit only intends to fix it for when ENV_IS_NOWHERE.
