- * 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.
