NAND Flash verify across block boundaries

This patch addresses a problem when CONFIG_MTD_NAND_VERIFY_WRITE is
defined
and the write crosses a block boundary. The pointer to the verification
buffer (bufstart) is not being updated to reflect the starting of the
new
block so the verification of the second block fails.

CHANGELOG:

* Fix NAND FLASH page verification across block boundaries
