Subject: imx8mn and HAB

Hi,

We use mainline TF-A and have problems using the HAB API in the U-Boot. We see for example that the hab_auth_img command fails in the mainline U-Boot. If we switch to the downstream NXP TF-A it works. Is this to be expected?

Upstream TF-A has not include HAB support, so when uboot call HAB SIP to ATF, TF-A will return failure.

Ah ok, i see. Thanks for the explanation. Is there a reason why this is not enabled in mainline TF-A?

Regards, Peng.
