Hi all, With a lot of helps from the TF-M team, I have prepared a Trusted Firmware-M Technical Overview document, available here: https://www.trustedfirmware.org/blog/TF-M-TechOverview/ In addition to various general concepts about Trusted Firmware-M, this document also introduces several new features in TF-M v1.7.

Thanks to the TF-M team for their helps in preparing this document! :-) Regards, Joseph
