[PATCH v2 0/8] mtd: rawnand: bcm47xx: Convert to exec_op() (and more)

[Boris Brezillon <boris.brezillon@xxxxxxxxxxxxx>]

Hello,

A bit of context to explain the motivation behind those conversions
I've been sending for the last couple of weeks. 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 BCM47XX NAND controller driver to
exec_op(), plus a bunch of minor improvements done along the way.
I hope I'll find someone to test those changes, but if there's no one
still having access to this  HW or no interest in keeping it supported
in recent kernel versions, we should definitely consider removing the
driver instead.

No major changes in this v2, apart from fixes for things reported by
Miquel. See the changelog on each patch for more details.

Regards,

Boris
