Ard Biesheuvel 982aa6a18e ArmPlatformPkg/Sec: remove global variable allocation from lowlevel init
Now that we dropped all ArmPlatformGlobalVariableLib dependencies,
there is no longer a need to allocate and clear out the global
variable region in the Sec init code. So remove it.

Samer El-Haj-Mahmoud b1179c1929 ArmPlatformPkg: Allow PcdFirmwareVersionString to be a dynamic PCD
PcdFirmwareVersionString is defined in MdeModulePkg to be
either fixed or dynamic, but is restricted in ArmPlatformPkg
drivers to FixedPcd. Changed to remove the FixedPcd
restrictions to allow platforms to chose the correct type
in their DSC files.

Leif Lindholm bb5420bb2b ArmPlatformPkg: Increase more ARM address Pcd entries to 64-bit.
Some AArch64 platforms have RAM and flash devices >4GB.
Update some additional Pcd entries to 64-bit, and change

oliviermartin 8d0fe26cbf ArmPlatformPkg: Remove ArmPlatformBootRemapping() function from the ArmPlatformLib
Memory map remapping is a platform specific feature only enabled by some platforms.
Instead of keeping this function empty for most platforms, the function has been
removed. This feature can easily fit in any other ArmPlatformLib function.
