Trusted Firmware-A - version 1.4
Trusted Firmware-A - version 1.5
================================
Trusted Firmware-A (TF-A) provides a reference implementation of secure world
software for `Armv8-A`_, including a `Secure Monitor`_ executing at Exception
Level 3 (EL3). It implements various Arm interface standards, such as:
software for `Armv7-A and Armv8-A`_, including a `Secure Monitor`_ executing
at Exception Level 3 (EL3). It implements various Arm interface standards,
such as:
- The `Power State Coordination Interface (PSCI)`_
- Trusted Board Boot Requirements (TBBR, Arm DEN0006C-1)
- `SMC Calling Convention`_
- `System Control and Management Interface`_
- `Software Delegated Exception Interface (SDEI)`_
As far as possible the code is designed for reuse or porting to other Armv8-A
model and hardware platforms.
Where possible, the code is designed for reuse or porting to other Armv7-A and
Armv8-A model and hardware platforms.
Arm will continue development in collaboration with interested parties to
provide a full reference implementation of Secure Monitor code and Arm standards
to the benefit of all developers working with Armv8-A TrustZone technology.
