We can clean up the loop logic a bit, here. This refactoring was enabled
in part by:

This patch is simply an added warning in the comments. Ideally, this patch
need not be merged, but rather, a developer will write a proper solution
that can use the ecc.read_oob_raw and ecc.write_oob_raw interfaces.

I think you can just remove the following paragraph(it's out of date now).

I've pushed Brian's patch to l2-mtd.git - it is OK in this form and I
think it is better if someone who takes care of gpmi fixes-up the
comments properly instead.
