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?

No special reason, due to time slot before. I have resume the upstream task to clean up the internal patches.

Ok. Sounds good to me. But I assume that it won't make it into the next upstream release (end of May). So I guess we have to switch to the downstream NXP fork to use this feature.

Right, can NOT catch up the release of May.
