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.

52	  This is the total length of the mapping of the flash chips on
53	  your particular board. If there is space, or aliases, in the
54	  physical memory map between the chips, this could be larger
55	  than the total amount of flash present. Refer to the memory
