I had actually smoke-tested it on my laptop:

[    0.000000] Linux version 5.0.0-rc8-panda (muriloo@localhost) (gcc version 6.4.0 (Buildroot 2018.02-rc2-00006-g39101b7)) #1 SMP Mon Feb 25 11:00:15 -03 2019
[    0.000000] Found initrd at 0xc000000060000000:0xc0000000601e6cfc

My patches apply smoothly on top of your powernv-4.0 branch, in case you're
willing to give it a try.

Let's chat offline to get it tested on a p9 machine.

Thanks for the review!
