Hi,
NS Agent is a TF-M implementation-defined component instead of the FF-M compliant one. Hence it can have necessary customization.
TF-M needs to deal with standard FF-M components (Secure Partition) and their manifests in the FF-M defined ways, in case these Secure Partitions are ported from other implementations. But it is not expected that someone would port TF-M NS Agent to another implementation without tweaking. (It would be nice if someone can provide this compatibility 😉).

In https://lists.trustedfirmware.org/archives/list/tf-m@lists.trustedfirmware.o... Ken mentions the need for a special flag in the manifest to indicate a non-secure agent partition. The code change is fairly easy, I think, but the manifest file format is specified by PSA, and presumably would also need to change.
How do we go about doing that?
Thanks,
Chris Brand
