Trusted Firmware A provides a reference implementation of secure world software for Armv8-A application class processors. It provides SoC developers and OEMs with a reference trusted code base complying with the relevant Arm specifications, allowing quick and easy porting to modern chips and platforms which forms the foundations of a Trusted Execution Environment (TEE) on application class processors.

The Trusted Firmware A project is an open governance community project hosted by Linaro where membership of the Trusted Firmware project is open to all with governance overseen by a board of member representatives. This project operates under under a BSD-3-Clause license and contributions are accepted under the term of Developer Certificate of Origin

This technical overview will cover the secure bootflow, secure monitor and exception level architecture support supplied by the reference implementation which supports various Arm interface standards, such as:

Power State Coordination Interface (PSCI)
Trusted Board Boot Requirements (TBBR)
SMC Calling Convention (SMCCC)
System Control and Management Interface (SCMI)
Software Delegated Exception Interface (SDEI)
