config MTD_COMPLEX_MAPPINGS
        bool "Support non-linear mappings of flash chips"
        help
          This causes the chip drivers to allow for complicated
          paged mappings of flash chips.

config MTD_PHYSMAP
        tristate "CFI Flash device in physical memory map"
        depends on MTD_CFI || MTD_JEDECPROBE || MTD_ROM
        help
          This provides a 'mapping' driver which allows the NOR Flash and
          ROM driver code to communicate with 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.

config MTD_PHYSMAP_START
        hex "Physical start address of flash mapping"
        depends on MTD_PHYSMAP
        default "0x8000000"
        help
          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()).

config MTD_PHYSMAP_LEN
        hex "Physical length of flash mapping"
        depends on MTD_PHYSMAP
        default "0"
        help
          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()).

config MTD_PHYSMAP_BANKWIDTH
        int "Bank width in octets"
        depends on MTD_PHYSMAP
        default "2"
        help
          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 octet 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()).

          ROM driver code to communicate with chips which are mapped
          physically into the CPU's memory. The mapping description here is
          taken from OF device tree.

          which user-programmable flash chips are connected on various
          Sun Microsystems boardsets.  This driver will require CFI support
