Thanks Chasel for the feedback. I've sent patch v2 with changes according to your comment. Can you please review it again?

Hi Ted,
One question below inline.
Another minor feedback is the commit/patch subject format should be "Package: title"
Thanks,
Chasel

Is child FV always with EFI_SECTION_TYPE.RAW? Or it could be other types like EFI_SECTION_TYPE.FIRMWARE_VOLUME_IMAGE?
