+         Most armv8 systems have PSCI support enabled in EL3, either through
+         ARM Trusted Firmware or other firmware.
+
+         On these systems, we do not need to implement system reset manually,
+         but can instead rely on higher level firmware to deal with it.
+
+         Select Y here to make use of PSCI calls for system reset
