Agilex 5 HPS TEE

Hi, 

Is Arm Trust Zone supported on HPS? If so is the implementation of TEE supported on Agilex 5? I've checked TF-A sources and it seems that BL2 on this platform loads only BL31 and BL33. How about BL32?

Is there an OP-TEE support? If not, are there any plans to provide it in the nearest feature?

    May I know, what kind of use-cases you are intending to use the OP-TEE OS BL32 for?  This will give us some inputs/feedbacks on our roadmap. Thanks

      Hi, thanks. OP-TEE Secure Storage through RPMB would be useful :)

    Hi rdrr,

    We don't have a ready-to-go OPTEE design example for Agilex 5 right now, but it is on our roadmap. Depending on your timeline, this may be a project we can develop with your input.

    Our hardware and AFT can support OPTEE, but today you would need to make the ATF changes required yourself.
