or is this what should go in the mc structure instead?

No. It will just be hard to get this done right and in time.

Well, meminit code knows what memory controller it is written for. AMD
wont start building CPUs using 2:23.0 instead of 0:18.0

On most systems the mem controller is 0:0.0 anyways.

> I think the tree should have several ctrl nodes - one per MC. Right?

yes. It has but they are "ordinary pci devices" in the tree. we dont
have a tree at raminit time (yet?)
