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