hold a microcode) whose address as the first entry in the topswap FIT.
This is useful in creating a asymmetric FIT in top swap bootblock
than the one in non-topswap bootblock. This string will be passed
onto cbfstool (-q option). cbfstool will not parse the region for MCU
onto ifittool (-A -n option). ifittool will not parse the region for MCU
entries, and only locate the region and insert its address into FIT.
