1.For EFI_FIRMWARE_MANAGEMENT_PROTOCOL.GetImage(): Add the following sentence at the end of the Image parameter description. "May be NULL with a zero ImageSize in order to determine the size of the buffer needed".
Modify the description of "EFI_INVALID_PARAMETER" return code as "The ImageSize is not too small and Image is NULL." 2.For EFI_FIRMWARE_MANAGEMENT_PROTOCOL.GetImageInfo(): Add the following sentence at the end of the ImageInfo parameter description."May be NULL with a zero ImageInfoSize in order to determine the size of the buffer needed". Modify the description of "EFI_INVALID_PARAMETER" return code as "The ImageInfoSize is not too small and Image is NULL." and add new descriptions for "EFI_INVALID_PARAMETER" return code.
