The FF-A v1.0 spec allows two configurations for the number of EC/vCPU instantiated in a Secure Partition: -A MultiProcessor (MP) SP instantiates as many ECs as the number of PEs. An EC is pinned to a corresponding physical CPU. -An UniProcessor (UP) SP instantiates a single EC. The EC is migrated to the physical CPU from which the FF-A call is originating. This change permits exercising the latter case within the TF-A-tests framework. Signed-off-by: Olivier Deprez <olivier.deprez@arm.com> Change-Id: I7fae0e7b873f349b34e57de5cea496210123aea0
