I understand Thomas's point as as he is fighting for generalization.
Indeed, this OOB stuff introduces a lot of mess.

Charles' point is - if OOB is there, why not to let users use it? Also
sounds reasonable.

What I think would be nice to do is to get rid of OOB in MTD stuff, but
add a possibility to access OOB via some NAND-specific interfaces from
nand_base. Indeed, if one wants to work with a generalized flash device
- please use MTD interface. If one still wants to access OOB, use
lower-layer NAND interfaces. That's all about to have more then one
layer of Generalization. And I believe this is the right way to go.
