TF-M has been under active development since it was launched in Q1'18. It is being designed to include
1. //**Secure boot**// ensuring integrity of runtime images and responsible for firmware upgrade.
2. Runtime firmware consisting of
//** TF-M Core**// responsible for secure isolation, execution and communication aspects. and a set of Secure Services
providing services to the Non-Secure and Secure Applications. The secures services currently planned to be supported are
//**Secure Storage, Cryptography, Audit Logs, Attestation, Provisioning and Platform Services**//
Roadmap below shows when the services are getting supported and then enhanced.
