+ 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.
