+	  Many flash memories support erasing small (4096 B) sectors. Depending
+	  on the usage this feature may provide performance gain in comparison
+	  to erasing whole blocks (32/64 KiB).
+	  Changing a small part of the flash's contents is usually faster with
+	  small sectors. On the other hand erasing should be faster when using
+	  64 KiB block instead of 16 × 4 KiB sectors.

+	  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
