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

54 map which should hopefully be in the documentation for your
57 config MTD_PHYSMAP_BANKWIDTH
58 int "Bank width in octets"
59 depends on MTD_PHYSMAP_COMPAT
