 438           This driver allows for discovery of PISMO modules - see
 439           <http://www.pismoworld.org/>.  These are small modules containing
 440           up to five memory devices (eg, SRAM, flash, DOC) described by an
 441           I2C EEPROM.
 442
 443           This driver does not create any MTD maps itself; instead it
 444           creates MTD physmap and MTD SRAM platform devices.  If you
 445           enable this option, you should consider enabling MTD_PHYSMAP
 446           and/or MTD_PLATRAM according to the devices on your module.
 447
 448           When built as a module, it will be called pismo.ko
