+         This enables support for accessing all type of OneNAND flash
+         devices. For further information see
+         <http://www.samsung.com/Products/Semiconductor/Flash/OneNAND_TM/index.htm>.

+       help
+         This adds an extra check when data is written to the flash. The
+         OneNAND flash device internally checks only bits transitioning
+         from 1 to 0. There is a rare possibility that even though the
+         device thinks the write was successful, a bit could have been
+         flipped accidentaly due to device wear or something else.

+         Support for OneNAND flash on TI OMAP board.
