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.

Alexander Graf (5):
  efi_loader: Allow boards to implement get_time and reset_system
  arm: Disable HVC PSCI calls by default
  arm: Add PSCI shutdown function
  arm: Provide common PSCI based reset handler
  efi_loader: Add generic PSCI RTS
