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.
