Subject: Add the database rebuild byte for the
 PP5022AF-05.51-S301-00.12-S301.00.12A-D OF version. Dont output the sector
 count so often when doing the partition dump. CAUTION: don't upgrade to this
 bootloader as the buttons still are not working in the bootloader (USB will
 be the only access to the OF if you do)
