* Put one of these structures in platform_data for SPI EEPROMS handled
* by the "at25" driver. On SPI, most EEPROMS understand the same core
* command set. If you need to support EEPROMs that don't yet fit, add
* flags to support those protocol options. These values all come from
* the chip datasheets.
