Routine Description:
This service is called from Index == 0 until it returns EFI_UNSUPPORTED.
It allows discontiguous memory regions to be supported by the emulator.
It uses gSystemMemory[] and gSystemMemoryCount that were created by
parsing the Windows environment variable EFI_MEMORY_SIZE.
The size comes from the varaible and the address comes from the call to
WinNtOpenFile.
Arguments:
Index - Which memory region to use
MemoryBase - Return Base address of memory region
MemorySize - Return size in bytes of the memory region
Returns:
EFI_SUCCESS - If memory region was mapped
EFI_UNSUPPORTED - If Index is not supported
