The System Memory region might be out of the 32-bit memory space.
This change has been validated on the FVP AArch64 model using 4GB
of DRAM at 0x8_0000_0000:
- # System Memory (2GB)
- gArmTokenSpaceGuid.PcdSystemMemoryBase|0x80000000
- gArmTokenSpaceGuid.PcdSystemMemorySize|0x80000000
+ # System Memory (4GB)
+ gArmTokenSpaceGuid.PcdSystemMemoryBase|0x800000000
+ gArmTokenSpaceGuid.PcdSystemMemorySize|0x100000000
EFI Shell and Linux kernel boot successfully.
Note: This change has not been validated on AArch32. I expect some
early assembly code to not work.

Setting bit4 of SCC register 48 now triggers the erasing of the memory region
reserved for variable storage in NOR flash and the restoration of the default
headers in flash.

The idea is to keep ArmPkg responsible for the ARM architectural modules and ArmPlatformPkg
the ARM development platform packages (with their respective drivers).
ArmPlatformPkg: Reduce driver dependency on ArmPlatform.h
- Move some driver definitions from C-Macro to PCD values
- Unify PCD driver namespace

This driver implements the interface for the PL111 Lcd controller.
The LcdPlatformLib allows to set the platform specific requirements
needed by the platform for setting the LCD (oscillators, etc).
ArmPlatformPkg/ArmVExpressPkg: Implement LcdPlatformLib
This library exports the supported resolutions. It also allocates the
memory for the framebuffer and send the correct settings to the VExpress
motherboard microcontroller.

This file contains the ARM Versatile Express motherboard definitions.
It allows to avoid duplication between different platforms based on ARM VExpress
motherboard.
