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. | |
