Hello,

+config MTD_ONENAND_VERIFY_WRITE
+       bool "Verify OneNAND page writes"
+       depends on MTD_ONENAND
+       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.

Why general MTD  CONFIG_MTD_NAND_VERIFY_WRITE config option and -
>verify_buf driver method (see nand_base.c) is not enough and you need
your own verify option?
