Exactly. If I shift the pointer by 4 bytes from within PrePiLib the device
boots just fine.
I'm not sure if the size is the root cause but right now it only happens
when adding a ~15mb binary efi to the end of fvmain.

You mean to dissect the FFS that contains the FV? Not sure.
So the _FVH signature is there but shifted by 4 bytes, right? Does
that only happen with large FVs?
