 Trusted Firmware-A (TF-A) provides a reference implementation of secure world
 software for `Armv7-A and Armv8-A`_, including a `Secure Monitor`_ executing
 at Exception Level 3 (EL3). It implements various Arm interface standards,
@@ -43,232 +40,45 @@ states.
 Users are encouraged to do their own security validation, including penetration
 testing, on any secure world code derived from TF-A.
 
-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 Armv7-A and Armv8-A TrustZone
-technology.
-
-Functionality
--------------
-
--  Initialization of the secure world, for example exception vectors, control
-   registers and interrupts for the platform.
-
--  Library support for CPU specific reset and power down sequences. This
-   includes support for errata workarounds and the latest Arm DynamIQ CPUs.
-
--  Drivers to enable standard initialization of Arm System IP, for example
-   Generic Interrupt Controller (GIC), Cache Coherent Interconnect (CCI),
-   Cache Coherent Network (CCN), Network Interconnect (NIC) and TrustZone
-   Controller (TZC).
-
--  A generic `SCMI`_ driver to interface with conforming power controllers, for
-   example the Arm System Control Processor (SCP).
-
--  SMC (Secure Monitor Call) handling, conforming to the `SMC Calling
-   Convention`_ using an EL3 runtime services framework.
-
--  `PSCI`_ library support for CPU, cluster and system power management
-   use-cases.
-   This library is pre-integrated with the AArch64 EL3 Runtime Software, and
-   is also suitable for integration with other AArch32 EL3 Runtime Software,
-   for example an AArch32 Secure OS.
-
--  A minimal AArch32 Secure Payload (SP\_MIN) to demonstrate `PSCI`_ library
-   integration with AArch32 EL3 Runtime Software.
-
--  Secure Monitor library code such as world switching, EL1 context management
-   and interrupt routing.
-   When a Secure-EL1 Payload (SP) is present, for example a Secure OS, the
-   AArch64 EL3 Runtime Software must be integrated with a Secure Payload
-   Dispatcher (SPD) component to customize the interaction with the SP.
-
--  A Test SP and SPD to demonstrate AArch64 Secure Monitor functionality and SP
-   interaction with PSCI.
-
--  SPDs for the `OP-TEE Secure OS`_, `NVIDIA Trusted Little Kernel`_
-   and `Trusty Secure OS`_.
-
--  A Trusted Board Boot implementation, conforming to all mandatory TBBR
-   requirements. This includes image authentication, Firmware Update (or
-   recovery mode), and packaging of the various firmware images into a
-   Firmware Image Package (FIP).
-
--  Pre-integration of TBB with the Arm CryptoCell product, to take advantage of
-   its hardware Root of Trust and crypto acceleration services.
-
--  Reliability, Availability, and Serviceability (RAS) functionality, including
-
-   -  A Secure Partition Manager (SPM) to manage Secure Partitions in
-      Secure-EL0, which can be used to implement simple management and
-      security services.
-
-   -  An |SDEI| dispatcher to route interrupt-based |SDEI| events.
-
-   -  An Exception Handling Framework (EHF) that allows dispatching of EL3
-      interrupts to their registered handlers, to facilitate firmware-first
-      error handling.
-
--  A dynamic configuration framework that enables each of the firmware images
-   to be configured at runtime if required by the platform. It also enables
-   loading of a hardware configuration (for example, a kernel device tree)
-   as part of the FIP, to be passed through the firmware stages.
-
--  Support for alternative boot flows, for example to support platforms where
-   the EL3 Runtime Software is loaded using other firmware or a separate
-   secure system processor, or where a non-TF-A ROM expects BL2 to be loaded
-   at EL3.
-
--  Support for the GCC, LLVM and Arm Compiler 6 toolchains.
-
--  Support for combining several libraries into a "romlib" image that may be
-   shared across images to reduce memory footprint. The romlib image is stored
-   in ROM but is accessed through a jump-table that may be stored
-   in read-write memory, allowing for the library code to be patched.
-
--  A prototype implementation of a Secure Partition Manager (SPM) that is based
-   on the SPCI Alpha 1 and SPRT draft specifications.
-
--  Support for ARMv8.3 pointer authentication in the normal and secure worlds.
-   The use of pointer authentication in the normal world is enabled whenever
-   architectural support is available, without the need for additional build
-   flags. Use of pointer authentication in the secure world remains an
-   experimental configuration at this time and requires the ``ENABLE_PAUTH``
-   build flag to be set.
+In collaboration with interested parties, we will continue to enhance |TF-A|
+with reference implementations of Arm standards to benefit developers working
+with Armv7-A and Armv8-A TrustZone technology.
 
--  Position-Independent Executable (PIE) support. Initially for BL31 only, with
-   further support to be added in a future release.
-
-For a full description of functionality and implementation details, please
-see the `Firmware Design`_ and supporting documentation. The `Change Log`_
-provides details of changes made since the last release.
