Re: [PATCH v2] ARM: hw_breakpoint: v7.1 self-hosted debug powerdown support

This patch introduces os save and restore mechanism for v7.1 debug and self-hosted debuggers. It enables the os to save DBGDSCR before powerdown and restore it when power is restored.

The clearing of the os lock in the restore function kick-starts the debug logic again.

The os save and restore routines are hooked into the CPU PM event notifier chain. CPU PM events are used to save and restore per-cpu context when a single CPU is preparing to enter or has exited a low power state.
