The current ArmVirtMemoryInitPeiLib code splits the memory region passed via PcdSystemMemoryBase/PcdSystemMemorySize in two if the region extends beyond the MAX_ADDRESS limit. This was introduced for 32-bit ARM, which may support more than 4 GB of physical address space, but cannot address all of it via a 1:1 mapping, and a single region that is not mappable in its entirety is unusable by the PEI core. AArch64 is in a similar situation now: platforms may support more than 256 TB of physical address space, but only 256 TB is addressable by the CPU, and so a memory region that extends from below this limit to above it should be split.
