ROM/Flash Initialization
There are two methods of injecting code into the Flash in bank A:
1. In-circuit programming
2. Loading it from ROM/Flash bank B
For the second method, hardware must direct the Falcon chip set to map
the FFF00000-FFFFFFFF address range to Flash bank B following a hard
reset. Bank A then can be programmed by code from bank B.
Software can determine the mapping of the FFF00000-FFFFFFFF address
range by examining the rom_b_rv bit in the Falcon’s Rom B Base/Size
register.
