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

> 主题: [edk2-devel] [PATCH v3 00/13] Add support for using FF-A calls
>
>
> 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.

> Changes since V2:
> * Added a STATIC storage class specifier for mSpmMajorVer and
> mSpmMinorVer variables
> * Added a STATIC storage class specifier for mSpmMajorVerFfa and
> mSpmMinorVerFfa variables
> * Add braces for if/else statements
> * Add a check for EFI_NOT_FOUND as a possible return value from
> LocateStandaloneMmCorePeCoffData in _ModuleEntryPoint function
> * Check for the return value in Arg0 after the Direct Request call to

> the memory attributes
> * Check for the return value in Arg0 after the Direct Request call to

> * Put a comment to reflect the fact that FFA_INTERRUPT and FFA_SUCCESS
