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

556	  This driver does not create any MTD maps itself; instead it

558	  enable this option, you should consider enabling MTD_PHYSMAP
559	  and/or MTD_PLATRAM according to the devices on your module.
