  42 Routine Description:
  43   Return the FD Size and base address. Since the FD is loaded from a
  44   file into host memory only the SEC will know it's address.
  45
  46 Arguments:
  47   Index  - Which FD, starts at zero.
  48   FdSize - Size of the FD in bytes
  49   FdBase - Start address of the FD. Assume it points to an FV Header
  50
  51 Returns:
  52   EFI_SUCCESS     - Return the Base address and size of the FV
  53   EFI_UNSUPPORTED - Index does nto map to an FD in the system
