Do you have a git tree for this patchset ?
Yes, but nothing public. I can set up a github fork if you want.

ok.
It would be nice to be able to download the images from some site
like we do for Aspeed.
It looks like Joel got this covered for gsj. I'll look into setting something up for npcm750-evb.

I have revived a PPC64 host. We might want to add the swapping back.
OK.
