Sughosh:
  This is a new feature. Can you submit one BZ
(https://bugzilla.tianocore.org/) to record it?

Thanks

> 
> 
> The following patch series adds support for using the Firmware
> Framework(FF-A) as a transport mechanism for requesting services from
> the Secure Partition Manager(SPM). This is done through a Pcd which
> can be used to enable the FF-A mechanism or to use the earlier used
> SVC calls.
