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