+         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

+         protocols during enumeration.
