The raw NAND subsystem carries a lot of history which makes any rework not only painful, but also subject to regressions which we only detect when someone dares to update its kernel on one of those ancient HW. While carrying drivers for old HW is not a problem per se, carrying ancient and unmaintained drivers that are not converted to new APIs is a maintenance burden, hence this massive conversion attempt I'm conducting here. So here is a series converting the Davinci NAND controller driver to exec_op(), plus a bunch of minor improvements done along the way.
