Hello,

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.

Regards, Nick

CHANGELOG:

* Fix NAND FLASH page verification across block boundaries
