This provides a 'mapping' driver which allows the NOR Flash and

ROM driver code to communicate with chips which are mapped

physically into the CPU's memory. You will need to configure

the physical address and size of the flash chips on your

particular board as well as the bus width, either statically

with config options or at run-time.
