Sometimes DataFlash chips are packaged inside MMC-format
cards; at this writing, the MMC stack won't handle those.

- This enables access to the DataFlash chip (AT26xxx) on an
- AT91RM9200-based board.
- If you have such a board and such a DataFlash, say 'Y'.

+ Spansion S25SL, SST 25VF, ST M25P, and Winbond W25X. Other chips

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