Routine Description:\r
  \r
  Given an EFI image filename, create a ROM-able image by creating an option \r
  ROM header and PCI data structure, filling them in, and then writing the\r
  option ROM header + PCI data structure + EFI image out to the output file.\r
\r
Arguments:\r
\r
  Argc            - standard C main() argument count\r
\r
  Argv            - standard C main() argument list\r
\r
Returns:\r
\r
  0             success\r
  non-zero      otherwise\r
