Thanks.  Can you provide some additional background information on how
this is intended to work.  If multiple CBFS locations are found, is
there a chance of file name conflicts?  Is the fmap stuff used for
primary/backup rom images and if so how will seabios account for that
if it scans both images?

Also, can you describe the high level use case you had in mind.
