1 menu "Mapping drivers for chip access"
5 config MTD_COMPLEX_MAPPINGS
6 bool "Support non-linear mappings of flash chips"
8 This causes the chip drivers to allow for complicated
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
30 Setup a simple mapping via the Kconfig options. Normally the
31 physmap configuration options are done via your board's
34 If unsure, say N here.
36 config MTD_PHYSMAP_START
37 hex "Physical start address of flash mapping"
38 depends on MTD_PHYSMAP_COMPAT
41 This is the physical memory location at which the flash chips
42 are mapped on your particular target board. Refer to the
43 memory map which should hopefully be in the documentation for
46 config MTD_PHYSMAP_LEN
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.

102 depends on SPARC && MTD_CFI && PCI
104 This provides a 'mapping' driver which supports the way in
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.
110 tristate "CFI Flash device mapped on AMD SC520 CDP"
111 depends on (MELAN || COMPILE_TEST) && MTD_CFI
