| | | | | | | | | | | | The Secure Partition(SP) can request services from the Secure Partition Manager Core(SPMC) either through FF-A calls or through the existing SVC calls. Add a feature flag Pcd for enabling the FF-A method -- when this is set to FALSE, the SP uses the existing SVC calls for making the requests.
