[PATCH V2 0/6] powerpc: AMP support for 47x

[Dave Kleikamp]

These patches add Asynchonous MultiProcessing support for the 47x chipset.
This allows independent OS instances to run on separate cores.

V2:
 1. Replace ugly hack in boot wrapper with generic solution

Dave Kleikamp (6):
  powerpc: Move udbg_early_init() after early_init_devtree()
  powerpc/44x: allow override to hard-coded uart address
  powerpc/47x: allow kernel to be loaded in higher physical memory
  powerpc/44x: don't use tlbivax on AMP systems
  powerpc/44x: boot wrapper: allow kernel to load into non-zero address
  powerpc/476: Create a dts files for two 476 AMP instances under ISS
