Huang, let me drop the 3 patches I already merged. Please, re-send them
in v5. I think this is better because I see you start applying patches
on top of them, which is a bit confusing.

I find this confusing still. How about this comment.

ECC correctability from the datasheet. Minumum amount of bit errors per
@ecc_size guaranteed to be correctable). If unknown, set to zero.

Silly question, why you call this one "ecc_size", and not "ecc_step"?
