Hi Martin. I was referring to PSA FF-M, not FF-A. See the spec here, in Section 2.1.

If the NSPE can use all the ARMv8-M processors, then it makes sense to use a model similar to ARMv8-A. In that model, the request for a secure service is usually handled by the local core - no cross core interaction.

Hi David. What about a scenario where non-secure applications want to use both cores? I think this is what Martin is asking about. Dedicating one M33 to act as a secure enclave can be considered a waste of compute resource (it will be idle most of the time).
