Just as Artem suggested:

"Both UBI and JFFS2 are able to read verify what they wrote already.
There are also MTD tests which do this verification. So I think there
is no reason to keep this in the NAND layer, let alone wasting RAM in
the driver to support this feature."

So kill MTD_NAND_VERIFY_WRITE entirely. Please see the patch:
http://lists.infradead.org/pipermail/linux-mtd/2012-August/043189.html
  
This patch removes the CONFIG_MTD_NAND_VERIFY_WRITE in the defconfigs.
