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.

70 depends on OF && (MTD_CFI || MTD_JEDECPROBE || MTD_ROM || MTD_RAM)
72 This provides a 'mapping' driver which allows the NOR Flash, ROM
73 and RAM driver code to communicate with chips which are mapped
74 physically into the CPU's memory. The mapping description here is
75 taken from OF device tree.

78 bool "Support ARM Versatile physmap OF"
79 depends on MTD_PHYSMAP_OF
81 default y if (ARCH_INTEGRATOR || ARCH_VERSATILE || ARCH_REALVIEW)
83 This provides some extra DT physmap parsing for the ARM Versatile
84 platforms, basically to add a VPP (write protection) callback so
85 the flash can be taken out of write protection.

110 config MTD_SUN_UFLASH
111 tristate "Sun Microsystems userflash support"
112 depends on SPARC && MTD_CFI && PCI
114 This provides a 'mapping' driver which supports the way in
115 which user-programmable flash chips are connected on various
116 Sun Microsystems boardsets. This driver will require CFI support
117 in the kernel, so if you did not enable CFI previously, do that now.
120 tristate "CFI Flash device mapped on AMD SC520 CDP"
121 depends on (MELAN || COMPILE_TEST) && MTD_CFI
123 The SC520 CDP board has two banks of CFI-compliant chips and one

141 This provides a driver for the on-board flash of the Technologic
142 System's TS-5500 board. The 2MB flash is split into 3 partitions
143 which are accessed as separate MTD devices.

146 flash disk (RFD) flash translation layer.
148 mtd1 allows you to reprogram your BIOS. BE VERY CAREFUL.
150 Note that jumper 3 ("Write Enable Drive A") must be set
151 otherwise detection won't succeed.
