[Pdbg] [PATCH v2 00/10] pdbg fixes for p9

Found and fixed a similar case where ramming would fail to cope with
the thread in stop (and would resume from the instruction after stop).

The register state for non-preserved registers when ramming a stopped
thread is not necessarily very sane, but at least this doesn't crash
the host so easily now if we try it.

Nicholas Piggin (10):
  libpdbg/p9chip.c: update timeouts for special wakeup and stop
  libpdbg/p9chip.c: remove sreset SRR1 workaround
  libpdbg/p9chip.c: use the OTR special wakeup status latch
  libpdbg/p9chip.c: do not fence interrupts when stopping threads
  libpdbg/p9chip.c: query thread active and stop states
  thread.c: threadstatus improve output and implement P9 stop
  libpdbg/p9chip.c: correct thread start for inactive and stopped
  libpdbg/p9chip: update thread status on stop, start, sreset
  libpdbg/p9chip.c: Add more steps to ram_setup
  libpdbg/p9chip.c: implement step support
