+ Use this config to specify the name of a FMAP region (which should
+ 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
+ entries, and only locate the region and insert its address into FIT.
