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.
21
22	  To compile this driver as a module, choose M here: the
23	  module will be called physmap.

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

63	  This is the total width of the data bus of the flash devices
64	  in octets. For example, if you have a data bus width of 32
65	  bits, you would set the bus width octet value to 4. This is
66	  used internally by the CFI drivers.
