Right, we'll continue to treat the f-segment as read-only after POST
even on coreboot.

Populate a "struct disk_op_s" and then call process_op() on it.  (You
will need to remove the ASSERT16 call from process_op.)  You can look
at cdrom_boot for an example (it calls cdb_read instead of process_op,
but the process is the same).
