+
+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 "Flash device in physical memory map"
+ depends on MTD_CFI || MTD_JEDECPROBE || MTD_ROM || MTD_RAM || MTD_LPDDR
+ 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.
+
+ To compile this driver as a module, choose M here: the
+ module will be called physmap.
+
+config MTD_PHYSMAP_COMPAT
+ bool "Physmap compat support"
+ depends on MTD_PHYSMAP
+ default n
+ help
+ Setup a simple mapping via the Kconfig options. Normally the
+ physmap configuration options are done via your board's

+
+config MTD_PHYSMAP_START

+ This is the physical memory location at which the flash chips

+ memory map which should hopefully be in the documentation for
+ your board.
+

+ hex "Physical length of flash mapping"
+ depends on MTD_PHYSMAP_COMPAT
+ 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.
+
+config MTD_PHYSMAP_BANKWIDTH
+ int "Bank width in octets"
+ depends on MTD_PHYSMAP_COMPAT
+ 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.

+ help
+ This provides a 'mapping' driver which supports the way in
+ which user-programmable flash chips are connected on various

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