On aarch64 systems, Linux only has managed to push almost everyone to using PSCI as standardized interface for CPU start/stop operations. Fortunately PSCI also gives us a nicely abstracted interface to reset and power off the system.
This patch set adds support for generic PSCI reset/shutdown support and ties it up to EFI Run Time Services, so that an OS like Linux will magically have reset and shutdown work.
