PatchTrack

Again a first round completely internal. I still need to clean up the t-head defines and rework commit messages and maybe some comments a bit. But overall it's very satisfying to see the same kernel image boot on: - beaglev ... as before - qemu ... with the svpbmt qemu patch - d1-nezha ;-) So, comments welcome.
