  The entry point of PE/COFF Image for a PEIM.

  This function is the entry point for a PEIM.  This function must call ProcessLibraryConstructorList()

  If _gPeimRevision is not zero and PeiServices->Hdr.Revision is less than _gPeimRevison, then ASSERT().

  @param  FileHandle  Handle of the file being invoked. 
  @param  PeiServices Describes the list of possible PEI Services.

  @retval  EFI_SUCCESS   The PEIM executed normally.
  @retval  !EFI_SUCCESS  The PEIM failed to execute normally.

  instances that a module depends on indirectly through other libraries.
