Trusted Firmware M provides a reference implementation of secure world software for ARMv8-M. The TF-M itself is provided under a BSD-3-Clause.
Note
The software implementation contained in this project is designed to be a reference implementation of the Platform Security Architecture (PSA). It currently does not implement all the features of that architecture, however we expect the code to evolve along with the specifications.
