FEAT_MOPS, mandatory from Arm v8.8, is typically managed in EL2.
However, in configurations where NS_EL2 is not enabled,
EL3 must set the HCRX_EL2.MSCEn bit to 1 to enable the feature.
This patch ensures FEAT_MOPS is enabled by setting HCRX_EL2.MSCEn to 1.

For a couple of releases now we have officially withdrawn support for
building TF-A on Windows using the native environment, relying instead
on POSIX emulation layers like MSYS2, Mingw64, Cygwin or WSL.
This change removes the remainder of the OS compatibility layer
entirely, and migrates the build system over to explicitly relying on a
POSIX environment.

Initializing all early clocks before the MMU is enabled can impact boot
time. Therefore, splitting the setup into A53 clocks and peripheral
clocks can be beneficial, with the peripheral clocks configured after
fully initializing the MMU.

On some platforms plat_my_core_pos is a nontrivial function that takes a
bit of time and the compiler really doesn't like to inline. In the PSCI
library, at least, we have no need to keep repeatedly calling it and we
can instead pass it around as an argument. This saves on a lot of
redundant calls, speeding the library up a bit.

Include console names in the QEMU manifest to remain compatible with
RMM, just like commit aa99881d30 ("fix(rme): add console name to

Checksum calculation is done by adding together 64-bit values. Add a
helper that does this.

The commit
1922875233 ("fix(spm-mm): carve out NS buffer TZC400 region")
removes overlaps of ns shared buffer in secure memory region.
Unfortunately, this separation increases 1 region and over maximum
number of TZC programmable regions when they include
extended memory map regions (DRAM3 to DRAM6).
This causes boot failure of StandaloneMm with spmc_el3 && sp_el0 with
ASSERT: drivers/arm/tzc/tzc400.c:256.
To fix this, like SPM_MM, exclude setting extended memory map regions when
it uses SPMC_AT_EL3 && SPC_AT_EL3_SEL0_SP.

Support StandaloneMm running with FF-A as S-EL0 SP
when TF-A is built with EL3 SPMC partition manager.
For this
1. add manifest file describing StandaloneMm partition.
2. add number of page mapping area.
3. StandaloneMm should use SRAM with 512K.
while enabling, StandaloneMm, BL1 image requires more size:
aarch64-none-elf/bin/ld: BL31 image has exceeded its limit.
aarch64-none-elf/bin/ld: region `RAM' overflowed by 16384 bytes
So, when using SRAM size with 512K configuration,
increase size limit of BL1 binary.
