+ Enable the access for SPI-flash-based AT45xxx DataFlash chips.
+ DataFlash is a kind of SPI flash. Most AT45 chips have two buffers
+ in each chip, which may be used for double buffered I/O; but this
+ driver doesn't (yet) use these for any kind of i/o overlap or prefetching.
+
+ Sometimes DataFlash is packaged in MMC-format cards, although the
+ MMC stack can't (yet?) distinguish between MMC and DataFlash
+ protocols during enumeration.
