16 resides at EL3 and management services run from isolated Secure Partitions at S-EL0.
51 S-EL0 that can be used to implement simple management and security services.
52 Since S-EL0 is an unprivileged Exception Level, a Secure Partition relies on
67 services in EL3 and instantiate the rest in a partition in S-EL0.
