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.

66 bits, you would set the bus width octet value to 4. This is
67 used internally by the CFI drivers.
