[Joel Stanley <joel@xxxxxxxxx>]

Hey Chris,

I managed to build a kernel (took some stuffing about, nouveau wouldn't
build) here and give it a spin on an OpenPower box. From my minimal The
PRD and MTD functionality appears be good to go.

Where do we go from here? Are we able to get this into a -proposed
kernel so our test teams can do some verification?

Cheers
