(Commit 7cb777a3d7 (mtd: add ARM pismo support)
intended to add this, but seems only to have patched the Makefile without
touching Kconfig or providing any code...)
The following patch adds support for PISMO modules found on ARM Ltd
development platforms. These are MTD modules, and can have a
selection of SRAM, flash or DOC devices as described by an on-board
I2C EEPROM.
We support SRAM and NOR flash devices only by registering appropriate
conventional MTD platform devices as children of the 'pismo' device.

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
