Paul Beesley 8eb9490b61 doc: Move "About" content from index.rst to a new chapter 
The index.rst page is now the primary landing page for the TF-A
documentation. It contains quite a lot of content these days,
including:

- The project purpose and general intro
- A list of functionality
- A list of planned functionality
- A list of supported platforms
- "Getting started" links to other documents
- Contact information for raising issues

This patch creates an "About" chapter in the table
of contents and moves some content there. In order,
the above listed content:

- Stayed where it is. This is the right place for it.
- Moved to About->Features
- Moved to About->Features (in subsection)
- Stayed where it is. Moved in a later patch.
- Was expanded in-place
- Moved to About->Contact

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,
such as:
- The `Power State Coordination Interface (PSCI)`_
- `Trusted Board Boot Requirements CLIENT (TBBR-CLIENT)`_
- `SMC Calling Convention`_
- `System Control and Management Interface (SCMI)`_
- `Software Delegated Exception Interface (SDEI)`_
Where possible, the code is designed for reuse or porting to other Armv7-A and
Armv8-A model and hardware platforms.
This release provides a suitable starting point for productization of secure
world boot and runtime firmware, in either the AArch32 or AArch64 execution
states.
Users are encouraged to do their own security validation, including penetration
testing, on any secure world code derived from TF-A.
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.
Getting Started
---------------
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.
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.
Refer to the documents in the **Getting Started** chapter for information about
the prerequisites and requirements for building |TF-A|.
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).
The **Components** chapter holds documents that explain specific components
that make up the |TF-A| software, the :ref:`Exception Handling Framework`, for
example.
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.
**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.
The results of any performance evaluations are added to the
**Performance & Testing** chapter.
**Security Advisories** holds a list of documents relating to |CVE| entries that
have previously been raised against the software.
Platforms
---------
Various AArch32 and AArch64 builds of this release have been tested on r0, r1
and r2 variants of the `Juno Arm Development Platform`_.
