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