Hi TF-M committee,

I have a question regarding  PSA certification. Am I understanding correctly that if a platform wants to be ported to TF-M and the product wants to pass PSA certified, the TF-M version needs to come from a certain LTS tag release (e.g.TF-M v2.1.0 with commit 0c4c99b that was pushed 5 months ago). However,  Zephyr v3.7.0 is using TF-M version that is updated after TF-M v2.1.0. Does that means efforts need to be done to manually modify west.yml in Zephyr to roll back to the tag release of v2.1.0 for PSA certification?

Thank you very much,

Best,
