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

21 with config options or at run-time.
23 To compile this driver as a module, choose M here: the
24 module will be called physmap.
26 config MTD_PHYSMAP_COMPAT
27 bool "Physmap compat support"

51 depends on MTD_PHYSMAP_COMPAT
54 This is the total length of the mapping of the flash chips on
55 your particular board. If there is space, or aliases, in the
56 physical memory map between the chips, this could be larger
57 than the total amount of flash present. Refer to the memory
58 map which should hopefully be in the documentation for your
60 Ignore this option if you use run-time physmap configuration
61 (i.e., run-time calling physmap_configure()).
63 config MTD_PHYSMAP_BANKWIDTH
64 int "Bank width in octets"
65 depends on MTD_PHYSMAP_COMPAT
68 This is the total width of the data bus of the flash devices
69 in octets. For example, if you have a data bus width of 32
70 bits, you would set the bus width octet value to 4. This is
71 used internally by the CFI drivers.
72 Ignore this option if you use run-time physmap configuration
73 (i.e., run-time calling physmap_configure()).
