11 paged mappings of flash chips.
14 tristate "CFI Flash device in physical memory map"
15 depends on MTD_CFI || MTD_JEDECPROBE || MTD_ROM
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.
24 To compile this driver as a module, choose M here: the
25 module will be called physmap.
27 config MTD_PHYSMAP_START
28 hex "Physical start address of flash mapping"

32 This is the physical memory location at which the flash chips
33 are mapped on your particular target board. Refer to the

40 hex "Physical length of flash mapping"
41 depends on MTD_PHYSMAP
44 This is the total length of the mapping of the flash chips on
45 your particular board. If there is space, or aliases, in the
46 physical memory map between the chips, this could be larger
47 than the total amount of flash present. Refer to the memory
48 map which should hopefully be in the documentation for your
50 Ignore this option if you use run-time physmap configuration
51 (i.e., run-time calling physmap_configure()).
53 config MTD_PHYSMAP_BANKWIDTH
54 int "Bank width in octets"
55 depends on MTD_PHYSMAP
58 This is the total width of the data bus of the flash devices
59 in octets. For example, if you have a data bus width of 32
60 bits, you would set the bus width octet value to 4. This is
61 used internally by the CFI drivers.
62 Ignore this option if you use run-time physmap configuration
63 (i.e., run-time calling physmap_configure()).
