- Move isa/ppc* to sys/dev/ppc (repo-copy)
- Add an attachment method to ppc for puc
- In puc we need to walk the chain of parents.
Still to do, is to make ppc(4) & puc(4) work on other platforms. Testers
wanted.
PR: 38372 (in spirit done differently)
Verified by: Make universe (if I messed up a platform please fix)
