AM5716: Does AM5716 support tf-a / optee ?

Hello xia,

"The pre-built TF-A binary should be packaged in TI Processor SDK: <path-to-processor-sdk>/board-support/prebuilt-images/<optional-build-machine-name>/bl31.bin. Use this binary since it has been tested with TI Processor SDK."

https://software-dl.ti.com/processor-sdk-linux/esd/AM57X/09_02_00_133/exports/docs/linux/Foundational_Components_OPTEE.html

"The OP-TEE binary (bl32.bin/tee-pager_v2.bin) is bundled into tispl.bin and the following are the instructions to build:"

that means am5716 supports tf-a and optee, but I just not found bl31.bin(tf-a) and tispl.bin or bl32.bin/tee-pager_v2.bin in the released SDK 9

so I want to confirm the following:

These are files that are used to boot the HS-FS boards in K3 architecture and does not apply to AM57. This chapter unfortunately a migration hiccup from other platforms.

Does AM5716 support tf-a and optee in SDK 6.3 / SDK 9 ?   If so ,  is it restrict on only some of 5716 series  or all 5716 series support this feature ?

Yes, it supports secure boot only and the Runtime implementation can be done by the customers end with no native support from TI side.

is there a test on Ti EVM board as mentioned in the document listed above

I don't believe so, since the documentation you are referring to is for K3 devices only. (TDA4x and AM6x).
