Routine Description:
  Performs an x64 specific relocation fixup

Arguments:
  Reloc      - Pointer to the relocation record
  Fixup      - Pointer to the address to fix up
  FixupData  - Pointer to a buffer to log the fixups
  Adjust     - The offset to adjust the fixup

Returns:
  EFI_UNSUPPORTED - relocate unsupported

BOOLEAN
PeCoffLoaderImageFormatSupported (
  IN  UINT16  Machine
  )
/*++
Routine Description:

  Returns TRUE if the machine type of PE/COFF image is supported. Supported
  does not mean the image can be executed it means the PE/COFF loader supports
  loading and relocating of the image type. It's up to the caller to support
  the entry point.

  This function implies the basic PE/COFF loader/relocator supports IA32, EBC,
  & X64 images. Calling the entry point in a correct mannor is up to the
  consumer of this library.

Arguments:

  Machine   - Machine type from the PE Header.

Returns:

  TRUE      - if this PE/COFF loader can load the image
  FALSE     - if this PE/COFF loader cannot load the image
