+  Description: The drivers/mmcsd/mmcsd_sdio.c driver has hooks in place to
+               support read-ahead buffering and write buffering, but the logic
+               is incomplete and untested.

+  Description: A FLASH translation layer (FTL) has been implemented at
+               drivers/mtd/ftl.c but has not yet been tested.  This layer
+               will convert a FLASH MTD interface into a block driver that
+               can be used with any file system.  Good performance of this
+               layer will depend upon functioning write buffer support!
