14 help
15 This provides a 'mapping' driver which allows the NOR Flash and
16 ROM driver code to communicate with chips which are mapped
17 physically into the CPU's memory. You will need to configure
18 the physical address and size of the flash chips on your
19 particular board as well as the bus width, either statically
20 with config options or at run-time.

22 To compile this driver as a module, choose M here: the
