Mapping drivers for chip accessEdit

    • depends on MTD!=n


  • Option: MTD_COMPLEX_MAPPINGS
    • Kernel Versions: 2.6.15.6 ...
    • (on/off) Support non-linear mappings of flash chips
    • depends on MTD
      This causes the chip drivers to allow for complicated paged mappings of flash chips.


  • Option: MTD_PHYSMAP
    • Kernel Versions: 2.6.15.6 ...
    • (on/off/module) CFI Flash device in physical memory map
    • depends on MTD_CFI
      This provides a 'mapping' driver which allows the CFI probe and command set driver code to communicate with flash chips which are mapped physically into the CPU's memory. You will need to configure the physical address and size of the flash chips on your particular board as well as the bus width, either statically with config options or at run-time.


  • Option: MTD_PHYSMAP_START
    • Kernel Versions: 2.6.15.6 ...

"Physical start address of flash mapping"

    • depends on MTD_PHYSMAP
    • default "0x8000000"
      This is the physical memory location at which the flash chips are mapped on your particular target board. Refer to the memory map which should hopefully be in the documentation for your board. Ignore this option if you use run-time physmap configuration (i.e., run-time calling physmap_configure()).


  • Option: MTD_PHYSMAP_LEN
    • Kernel Versions: 2.6.15.6 ...

"Physical length of flash mapping"

    • depends on MTD_PHYSMAP
    • default "0x4000000"
      This is the total length of the mapping of the flash chips on your particular board. If there is space, or aliases, in the physical memory map between the chips, this could be larger than the total amount of flash present. Refer to the memory map which should hopefully be in the documentation for your board. Ignore this option if you use run-time physmap configuration (i.e., run-time calling physmap_configure()).


  • Option: MTD_PHYSMAP_BANKWIDTH
    • Kernel Versions: 2.6.15.6 ...

"Bank width in octets"

    • depends on MTD_PHYSMAP
    • default "2"
      This is the total width of the data bus of the flash devices in octets. For example, if you have a data bus width of 32 bits, you would set the bus width octect value to 4. This is used internally by the CFI drivers. Ignore this option if you use run-time physmap configuration (i.e., run-time calling physmap_configure()).


  • Option: MTD_SUN_UFLASH
    • Kernel Versions: 2.6.15.6 ...
    • (on/off/module) Sun Microsystems userflash support
    • depends on SPARC && MTD_CFI

    • depends on MTD_PCMCIA
    • default N
      If this option is enabled, PCMCIA cards which do not report anything about themselves are assumed to be MTD cards.
      If unsure, say N.
