Need to preserve previous ROM areas when writing a new image

[rminnich]

Some ROMs have areas not marked as "in use" that are in fact used. A common offender is AMD, which drops the ASP binary in an area of ROM not marked as used.

Just for the record, is the machine non-bootable if UTK removes the ASP/

[rjoleary]

UTK should be preserving all the sections. I'm concerned they put the ASP in the free space after the FV.

can I clarify, is this outside of all FVs? I think we do preserve this, so it must be a bug if it's being deleted. If it's between FV's this should be a BIOSPad region, which UTK preserves, look up biosregion.go.
