It provides a suitable starting point for\nproductization of secure world boot and runtime firmware, in either the AArch32\nor AArch64 execution states.\n\nTF-A implements Arm interface standards, including:\n\n-  `Power State Coordination Interface (PSCI)`_\n-  `Trusted Board Boot Requirements CLIENT (TBBR-CLIENT)`_\n-  `SMC Calling Convention`_\n-  `System Control and Management Interface (SCMI)`_\n-  `Software Delegated Exception Interface (SDEI)`_\n\nThe code is designed to be portable and reusable across hardware platforms and\nsoftware models that are based on the Armv8-A and Armv7-A architectures.\n\nIn collaboration with interested parties, we will continue to enhance TF-A\nwith reference implementations of Arm standards to benefit developers working\nwith Armv7-A and Armv8-A TrustZone technology.\n\nUsers are encouraged to do their own security validation, including penetration\ntesting, on any secure world code derived from TF-A.\n\nMore Info and Documentation\n---------------------------\n\nTo find out more about Trusted Firmware-A, please `view the full documentation`_\nthat is available through `trustedfirmware.org`_.\n\n--------------\n\n*Copyright (c) 2013-2019, Arm Limited and Contributors.
