 with reference implementations of Arm standards to benefit developers working

-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.
+Getting Started
+---------------
 
-   -  An Exception Handling Framework (EHF) that allows dispatching of EL3
-      interrupts to their registered handlers, to facilitate firmware-first
-      error handling.
+The |TF-A| documentation contains guidance for obtaining and building the
+software for existing, supported platforms, as well as supporting information
+for porting the software to a new platform.
 
--  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.
+The **About** chapter gives a high-level overview of |TF-A| features as well as
+some information on the project and how it is organized.
 
--  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.
+Refer to the documents in the **Getting Started** chapter for information about
+the prerequisites and requirements for building |TF-A|.
 
--  Support for the GCC, LLVM and Arm Compiler 6 toolchains.
+The **Processes & Policies** chapter explains the project's release schedule
+and process, how security disclosures are handled, and the guidelines for
+contributing to the project (including the coding style).
 
--  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.
+The **Components** chapter holds documents that explain specific components
+that make up the |TF-A| software, the :ref:`Exception Handling Framework`, for
+example.
 
--  A prototype implementation of a Secure Partition Manager (SPM) that is based
-   on the SPCI Alpha 1 and SPRT draft specifications.
+In the **System Design** chapter you will find documents that explain the
+design of portions of the software that involve more than one component, such
+as the :ref:`Trusted Board Boot` process.
 
--  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
-   ``BRANCH_PROTECTION`` option to be set to non-zero.
+**Platform Ports** provides a list of the supported hardware and software-model
+platforms that are supported upstream in |TF-A|. Most of these platforms also
+have additional documentation that has been provided by the maintainers of the
+platform.
 
--  Position-Independent Executable (PIE) support. Initially for BL31 only, with
-   further support to be added in a future release.
+The results of any performance evaluations are added to the
+**Performance & Testing** chapter.
