+Trusted Firmware-A Tests - version 2.3
+======================================
+
+The Trusted Firmware-A Tests (TF-A-Tests) is a suite of baremetal tests to
+exercise the `Trusted Firmware-A (TF-A)`_ features from the Normal World. It
+enables strong TF-A functional testing without dependency on a Rich OS. It
+mainly interacts with TF-A through its SMC interface.
+
+It provides a basis for TF-A developers to validate their own platform ports and
+add their own test cases.
+
+The following TF-A features are currently tested to some extent (this list is
+not exhaustive):
+
+- `SMC Calling Convention`_
+- `Power State Coordination Interface (PSCI)`_
+- `Software Delegated Exception Interface (SDEI)`_
+- `Performance Measurement Framework (PMF)`_
+- Communication and interaction with the `Test Secure Payload (TSP)`_
+- `Firmware update`_ (or recovery mode)
+- `EL3 payload`_ boot flow
+- `Secure partition`_ support
+
+These tests are not a compliance test suite for the Arm interface standards used
+in TF-A (such as PSCI).
+
+They do not cover 100% of the TF-A code. The fact that all tests pass does not
+mean that TF-A is free of bugs.
+
+They are not reference code. They should not be considered as the official way
+to test hardware/firmware features. Instead, they are provided as example code
+to experiment with and improve on.

+License
+-------
+
+The software is provided under a BSD-3-Clause `license`_. Contributions to this
+project are accepted under the same license with developer sign-off as
+described in the `Contributing Guidelines`_.
+
+This project contains code from other projects as listed below. The original
+license text is included in those source files.
+
+- The libc source code is derived from `FreeBSD`_ and `SCC`_. FreeBSD uses
+ various BSD licenses, including BSD-3-Clause and BSD-2-Clause. The SCC code
+ is used under the BSD-3-Clause license with the author's permission.
+
+- The `LLVM compiler-rt`_ source code is disjunctively dual licensed
+ (NCSA OR MIT). It is used by this project under the terms of the NCSA
+ license (also known as the University of Illinois/NCSA Open Source License),
+ which is a permissive license compatible with BSD-3-Clause. Any
+ contributions to this code must be made under the terms of both licenses.
+
+This release
+------------
+
+This release makes a wide range of tests available for validating the functionality
+of TF-A as well as several improvements to test framework and test suite.
+
+Please refer to the `change log`_ for more details of the features, known issues and
+limitations in the current release.
