ARM Trusted Firmware (ATF) 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: The Power State Coordination Interface (PSCI) Trusted Board Boot Requirements (TBBR, ARM DEN0006C-1) SMC Calling Convention System Control and Management Interface As far as possible the code is designed for reuse or porting to other 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. This package provides ATF for Allwinner H6 family SoCs.
