    Fix coreboot table size calculations.
    The code when reporting the coreboot table size did not account
    for the last added table record. This change fixes the problem.
     . rebuild coreboot, program it on the target, restart it
     . look for 'Wrote coreboot table at:' in the console log
     . observe the adequate table size reported
     $  grep 'Wrote coreboot table:' /tmp/cb.log
     Wrote coreboot table at: 00000500, 0x10 bytes, checksum c06f
     Wrote coreboot table at: 7f6fc000, 0x1a73 bytes, checksum 3e45
