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

51 int "Bank width in octets"
52 depends on MTD_PHYSMAP
55 This is the total width of the data bus of the flash devices
56 in octets. For example, if you have a data bus width of 32
57 bits, you would set the bus width octet value to 4. This is
58 used internally by the CFI drivers.
59 Ignore this option if you use run-time physmap configuration
60 (i.e., run-time calling physmap_configure()).
