9 paged mappings of flash chips.
12 tristate "Flash device in physical memory map"
13 depends on MTD_CFI || MTD_JEDECPROBE || MTD_ROM || MTD_LPDDR
15 This provides a 'mapping' driver which allows the NOR Flash and
16 ROM driver code to communicate with chips which are mapped
17 physically into the CPU's memory. You will need to configure
18 the physical address and size of the flash chips on your
19 particular board as well as the bus width, either statically
20 with config options or at run-time.
22 To compile this driver as a module, choose M here: the
23 module will be called physmap.
25 config MTD_PHYSMAP_COMPAT
26 bool "Physmap compat support"
27 depends on MTD_PHYSMAP

47 hex "Physical length of flash mapping"
48 depends on MTD_PHYSMAP_COMPAT
51 This is the total length of the mapping of the flash chips on
52 your particular board. If there is space, or aliases, in the
53 physical memory map between the chips, this could be larger
54 than the total amount of flash present. Refer to the memory
55 map which should hopefully be in the documentation for your
58 config MTD_PHYSMAP_BANKWIDTH
59 int "Bank width in octets"
60 depends on MTD_PHYSMAP_COMPAT
63 This is the total width of the data bus of the flash devices
64 in octets. For example, if you have a data bus width of 32
65 bits, you would set the bus width octet value to 4. This is
66 used internally by the CFI drivers.

105 which user-programmable flash chips are connected on various
106 Sun Microsystems boardsets. This driver will require CFI support
107 in the kernel, so if you did not enable CFI previously, do that now.
