I'm objecting, but not on the bit access reasons :).

1) Needs to go to the linux-mtd at lists.infradead.org list with the
maintainer CC'd (Thomas Gleixner)

2) I don't want this driver enabled in mainline for boards in
arch/powerpc until it fully understands how to parse device trees.

You could separate out the 8-bit access option and send that to
linux-mtd though
