Since v1:
- Rebased on upstream

Since v2:
- Fixed bug in deps traversal code that could cause some modules
  to not be probed.
- Tested and boots with little-endian patch on a P9.

Nicholas Piggin (2):
  Remove support for POWER8 DD1
  hw/slw: Move P8 bits behind CONFIG_P8

Stewart Smith (8):
  Introduce hwprobe facility to avoid hard-coding probe functions
  hwprobe: convert PHB, NPU subsystems to hwprobe
  Add CONFIG_P8 with PHB3 behind it
  hwprobe: convert vas_init(), nx_init()
  npu: move npu_set_fence_state() to phb_ops
  npu: Move npu.o and npu-hw-procedules.o under CONIFG_P8
  platforms: put P8 platforms behind CONFIG_P8
  npu: Add CONFIG_NPU to optionally skip NPU code
