- This enables access to most modern SPI flash chips, used for
- program and data storage. Series supported include Atmel AT26DF,
- Spansion S25SL, SST 25VF, ST M25P, and Winbond W25X. Other chips
- are supported as well. See the driver source for the current list,

- Note that the original DataFlash chips (AT45 series, not AT26DF),

- Set up your spi devices with the right board-specific platform data,

- doesn't support the JEDEC ID instruction.
