In linux kernel since version 2.6.29 (release Date: 2009-03-23)

Enable this driver to get read/write support to most SPI EEPROMs,
after you configure the board init code to know about each eeprom
on your target board.

This driver can also be built as a module. If so, the module
will be called at25.
