Assuming you're referring to FF-A support for the EDKII StandaloneMM partition, there was no upstream support until recently. FF-A support exists out of tree in Arm Neoverse solutions using Hafnium as an SPMC: https://neoverse-reference-design.docs.arm.com/en/latest/platforms/rdv3cfg1.... https://neoverse-reference-design.docs.arm.com/en/latest/releases/RD-INFRA-2... https://gitlab.arm.com/infra-solutions/reference-design/platsw/edk2/-/commit... Earlier RD N2 platform may support the same using the EL3 SPMC.

There is an on going upstreaming effort to which @Sami Mujawarmailto:Sami.Mujawar@arm.com may be able to share more details. Afaik EDKII changes are on list, and counterpart EL3 SPMC changes are in review: https://review.trustedfirmware.org/q/topic:%22hob_creation_in_tf_a%22+status...

Regards, Olivier.

Hello everyone,

I'm seeking a reference code for a Standalone Secure Partition using FF-A. Any guidance or suggestions would be greatly appreciated!

TIA, Akshay
