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.

+ One Block of the NAND Flash Array memory is reserved as
+ a One-Time Programmable Block memory area.
+ Also, 1st Block of NAND Flash Array can be used as OTP.

+ The OTP block can be read, programmed and locked using the same
+ operations as any other NAND Flash Array memory block.
+ OTP block cannot be erased.
+
+ OTP block is fully-guaranteed to be a valid block.
