Hi, I'm working on the BeagleBoneBlack port for UEFI. I am using the
PrePi as the entry point, and need some help with the call to
DecompressFirstFv().

I figure that FwVol.c:FfsAnyFvFindFirstFile() loops through each FV it
gets from the FV HOB and searches for
`EFI_FV_FILETYPE_FIRMWARE_VOLUME_IMAGE`, but I don't understand the
difference between searching for 'Next Volume' and 'Next File of the
type FIRMWARE_VOLUME_IMAGE'.

Are we assuming a definite layout of the FD for this to work?

Thanks,
Varad
