Idea here is to make faster scanning of erased page without bit flips.
For omap nand driver ecc reported by hardware is non-zero and non

So comparing with the standard vector for erased page and skipping

correction for erased page without bit flips.

So you mean that when you read a page, and you see there are bit-flips,
you start correcting them. But if you notice that the page is actually
an erased page, you optimize this case by not running the correction
machinery, but just filling the buffer with 0xFFs. Right?
