menu "Mapping drivers for chip access"
	depends on MTD!=n

config MTD_COMPLEX_MAPPINGS
	bool "Support non-linear mappings of flash chips"
	depends on MTD
	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
	help
	  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.

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 "0x4000000"
	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 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()).

config MTD_SUN_UFLASH
	tristate "Sun Microsystems userflash support"
	depends on (SPARC32 || SPARC64) && MTD_CFI
	help
	  This provides a 'mapping' driver which supports the way in

	depends on X86 && MTD_JEDECPROBE && MTD_PARTITIONS
	help
	  This provides a driver for the on-board flash of the Technologic
	  System's TS-5500 board. The flash is split into 3 partitions
	  which are accessed as separate MTD devices.

	  mtd0 and mtd2 are the two BIOS drives. Unfortunately the BIOS
	  uses a proprietary flash translation layer from General Software,
	  which is not supported (the drives cannot be mounted). You can
	  create your own file system (jffs for example), but the BIOS
	  won't be able to boot from it.

	  mtd1 allows you to reprogram your BIOS. BE VERY CAREFUL.

	  Note that jumper 3 ("Write Enable Drive A") must be set
	  otherwise detection won't succeeed.
