No bad block skipping?
Hmm... actually the 'left--' should be just after the 'if' block, otherwise not only will the code not skip a bad block, it will actually loop infinitely trying to read it. Will fix in v4. Thanks for pointing this out!
What causes read_single_page() to fail when there's a bad block marker? Especially if the marker is on a different page of the block. I'm not talking about ECC failures (which should not silently be skipped).
Oh gods, I see, sorry. I was indeed mixing up ECC errors and bad block markers. Show I'm really not good at NAND. :/
I'll look up how other drivers do it and add bad block skipping there.
