15	help
16	  This provides a 'mapping' driver which allows the NOR Flash and
17	  ROM driver code to communicate with chips which are mapped
18	  physically into the CPU's memory. You will need to configure
19	  the physical address and size of the flash chips on your
20	  particular board as well as the bus width, either statically
21	  with config options or at run-time.
22
23	  To compile this driver as a module, choose M here: the
24	  module will be called physmap.
