true, the answer to this problem may be to create a depgraph of the

boot.

That seems like a really smart idea. dtc could store the startup-order
and dependencies in the dtb someplace and the kernel can just run
through that. Using a combination of declaration order and
topo-phandle sorting would probably cover all cases???
