This chip is actually not an EEPROM, but a SPI nvSRAM. It can be 
interfaced by the at25 driver similar to an EEPROM. This is not the 
ideal solution, but it works until there's a proper driver for such 
chips. Maybe you can add some of these details to the commit message 
here. Also there is more information on this topic here:
