1Trusted Firmware-A
2==================
3
4Trusted Firmware-A (TF-A) is a reference implementation of secure world software
5for `Arm A-Profile architectures`_ (Armv8-A and Armv7-A), including an Exception
6Level 3 (EL3) `Secure Monitor`_. It provides a suitable starting point for
7productization of secure world boot and runtime firmware, in either the AArch32
8or AArch64 execution states.
9
10TF-A implements Arm interface standards, including:
11
12-  `Power State Coordination Interface (PSCI)`_
13-  `Trusted Board Boot Requirements CLIENT (TBBR-CLIENT)`_
14-  `SMC Calling Convention`_
15-  `System Control and Management Interface (SCMI)`_
16-  `Software Delegated Exception Interface (SDEI)`_
17
18The code is designed to be portable and reusable across hardware platforms and
19software models that are based on the Armv8-A and Armv7-A architectures.
20
21In collaboration with interested parties, we will continue to enhance TF-A
22with reference implementations of Arm standards to benefit developers working
23with Armv7-A and Armv8-A TrustZone technology.
24
25Users are encouraged to do their own security validation, including penetration
26testing, on any secure world code derived from TF-A.
