Moving UEFI firmware above this limit ensures some XIP runtime code (part of the
UEFI firmware) are not overwritten when loading Linux kernel.

The commit on Fri Dec 6 2013: "ArmPlatformPkg/ArmPlatformStackLib:
Do not directly use PcdArmPrimaryCore" has made the function
ArmPlatformStackSet() overwrites the registers r6 and r7.
These registers are used by PrePi to store the MPIDR and the the base
of the system memory region used by UEFI.

This patch adds an EDK2_ARMVE_SUPPORT_QEMU macro that can be defined at build
time to build an image that supports QEMU. The default build is unchanged and
builds the RTSM configuration.
QEMU only models fixed size blocks within a flash device, and the RTSM
configuration stores EFI variables in the smaller boot blocks of the
flash. When built for QEMU the larger blocks are used that QEMU properly
emulates.

At least for AARCH64 currently, SystemMemoryTop and FdTop can overflow
while adding the 32-bit PCDs together. The resulting value loses the
upper 32-bits. Cast each of the values to EFI_PHYSICAL_ADDRESS size
before doing the addition to prevent erroneous overflow. There is currently
no 32-bit platform in EDKII open source that will overflow and this change
would not fix that problem anyway.

modified the comment which can mislead.
The "ldr r0, [r1]" is overrided with a immediate "mov ro, #3"
instruction. This mov instruction will over write the contents
of the ro register. So replacing 'mov' by 'orr' instruction would
prevent to override the original value.
This patch assumes mov is the right instruction to be retained
