Routine Description:\r
  This service is called from Index == 0 until it returns EFI_UNSUPPORTED.\r
  It allows discontinuous memory regions to be supported by the emulator.\r
\r
Arguments:\r
  Index      - Which memory region to use\r
  MemoryBase - Return Base address of memory region\r
  MemorySize - Return size in bytes of the memory region\r
\r
Returns:\r
  EFI_SUCCESS - If memory region was mapped\r
  EFI_UNSUPPORTED - If Index is not supported\r

Routine Description:\r
  Return the FD Size and base address. Since the FD is loaded from a\r
  file into host memory only the SEC will know it's address.\r

Arguments:\r
  Index  - Which FD, starts at zero.\r
  FdSize - Size of the FD in bytes\r
  FdBase - Start address of the FD. Assume it points to an FV Header\r
  FixUp  - Difference between actual FD address and build address\r
\r
Returns:\r
  EFI_SUCCESS     - Return the Base address and size of the FV\r
  EFI_UNSUPPORTED - Index does nto map to an FD in the system\r
