235 - Interfaces that enable access to privileged operations from S-EL0. These
236   operations typically require access to system resources that are either shared
255 Hence, the SVC conduit must be used by the Secure Partition to access interfaces
402 that it needs access to and their attributes. The SPM validates this resource

609 access permissions of the memory regions are statically provided by the platform
