Most Dreamcast users will want to say Y here.

To build this as a module select M here, the module will be called

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
