  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.
  21
  22          To compile this driver as a module, choose M here: the
  23          module will be called physmap.

  54          than the total amount of flash present. Refer to the memory

 401          This driver allows for discovery of PISMO modules - see
 402          <http://www.pismoworld.org/>.  These are small modules containing
 403          up to five memory devices (eg, SRAM, flash, DOC) described by an
 404          I2C EEPROM.
 405
 406          This driver does not create any MTD maps itself; instead it
 407          creates MTD physmap and MTD SRAM platform devices.  If you
 408          enable this option, you should consider enabling MTD_PHYSMAP
 409          and/or MTD_PLATRAM according to the devices on your module.

 411          When built as a module, it will be called pismo.ko

 418          and have the upper address lines set by a board specific code.
 419
 420          If compiled as a module, it will be called latch-addr-flash.
