Create a new ArmVirtMemInfoLib for ArmVirtQemuKernel by cloning the existing ArmPlatformGetVirtualMemoryMap () for this platform, (ArmQemuRelocatablePlatformLib *not* ArmVirtPlatformLib), and cleaning it up: - remove support for uncached DRAM mappings - replace EFI_D_xxx with DEBUG_xxx throughout - use a temp variable to hold the top of the physical address space - use AllocatePool () instead of AllocatePages (), given that we use 160 bytes only, and the memory is never freed. In a future patch, we will add this library to the ordinary ArmVirtQemu platform as well.
