I'm not picking this patch to my l2-mtd-2.6.git, since AFAICS the chips
support ONFI should be detected properly.
The "older chips" which do not support reading ONFI data can then be
detected using special quirks. But using heuristics even for the chips
which do support reading ONFI data sounds bad.
Is this ok? :-)
Artem.
