Hi Brian,

Thanks, for pointing out! This is a very old comment, which needs to be updated. I will create a PR.

TF-M supports these profiles:

- PSA_IOT1 : This is deprecated, the plan to remove the support as soon as the psa-arch tests gets support for the PSA_2_0_0 profile.

- PSA_2_0_0: https://datatracker.ietf.org/doc/draft-tschofenig-rats-psa-token/24/

- ARM_CCA: https://datatracker.ietf.org/doc/draft-ffm-rats-cca-token/

Regards,

Tamas

Subject: [TF-M] attestation EAT version

Hi,

In TF-M v2.0, Initial_attestation.h says:

 * The initial attestation token is planned to be aligned with future version of

 * Entity Attestation Token format:

 * https://tools.ietf.org/html/draft-mandyam-eat-01

But that spec is expired and superceded with the following.

Is the implementation aligned with the following spec?  If so, what version of this spec is actually supported?
