The list of upstream platforms on the index page is growing
quite long, especially with all the FVP variants being listed
individually.
This patch leverages the "Platform Ports" chapter in the docs
table of contents to condense this information. Almost all
platform ports now have documentation, so the table of
contents serves as the list of upstream platforms by itself.
For those upstream platforms that do not have corresponding
documentation, the top-level "Platform Ports" page mentions
them individually. It also mentions each Arm FVP, just as
the index page did before.
Note that there is an in-progress patch that creates new
platform port documentation for the Arm Juno and Arm FVP
platforms, so this list of "other platforms" will soon be
reduced further as those platforms become part of the
table of contents as well.

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

The version of the Linaro release that is used for testing was
updated in 35010bb8 and the user guide was updated with the
correct version, however the version is also mentioned on the
index page and that was missed. Update the index page with the
new version.
We can come back and de-duplicate this content later, to ease
future maintenance.

The readme.rst and license.rst files in the project root overlap
with the index.rst and license.rst files in the docs/ folder. We
need to use the latter when building the documentation, as Sphinx
requires all included files to be under a common root. However,
the files in the root are currently used by the cgit and Github
viewers.
Using symlinks in Git presents some difficulties so the best
course of action is likely to leave these files but in stub form.
The license.rst file in the root will simply tell the reader to
refer to docs/license.rst.
The readme.rst file will contain a small amount of content that
is derived from the docs/index.rst file, so that the Github main
page will have something valid to show, but it will also contain
a link to the full documentation on ReadTheDocs.

Currently links between documents are using the format:
<path/to/><filename>.rst
This was required for services like GitHub because they render each
document in isolation - linking to another document is like linking
to any other file, just provide the full path.
However, with the new approach, the .rst files are only the raw
source for the documents. Once the documents have been rendered
the output is now in another format (HTML in our case) and so,
when linking to another document, the link must point to the
rendered version and not the .rst file.
The RST spec provides a few methods for linking between content.
The parent of this patch enabled the automatic creation of anchors
for document titles - we will use these anchors as the targets for
our links. Additional anchors can be added by hand if needed, on
section and sub-section titles, for example.
An example of this new format, for a document with the title
"Firmware Design" is :ref:`Firmware Design`.
One big advantage of this is that anchors are not dependent on
paths. We can then move documents around, even between directories,
without breaking any links between documents. Links will need to be
updated only if the title of a document changes.

The documentation contains plenty of notes and warnings. Enable
special rendering of these blocks by converting the note prefix
into a .. note:: annotation.

One of the current issues with the documentation is that terms and
abbreviations are frequently redefined. For example, we might have
a sentence like "... the SCP (System Control Processor) will ...".
These definitions might be repeated several times across pages, or
even within the same document. Equally, some of these abbreviations
are missed and are never expanded.
Sphinx provides a :term: keyword that takes some text and,
if that text is defined in a glossary document, links to its glossary
entry. Using this functionality will prevent repeated definitions
and will make the docs more maintainable by using a single
definition source.
The glossary added in this patch was created from a quick scrub of
the source code - there may be missing entries. The SDEI abbreviation
was used as an example.
Note that a global_substitutions file was created. This file contains
the RST 'replace' statements that convert plain text terms into linked
terms (by adding the ':term:' keyword to them). An example is:
.. |TF-A| replace:: :term:`TF-A`
The 'rst_prolog' variable in conf.py is used to inject this list of
replacements into each page. Terms must be surrounded with the pipe
character to be turned into links - this means that we can still
prevent certain terms from being linked if we don't want them to be.

These are no longer needed as there will always be a table of contents
rendered to the left of every page.
Some of these lists can be quite long and, when opening a page, the
reader sees nothing but a huge list of contents! After this patch,
the document contents are front-and-centre and the contents are
nicely rendered in the sidebar without duplication.

This patch attempts to standardise the document titles as well as
adding titles to documents that were missing one. The aim is to
remove needless references to "TF-A" or "Trusted Firmware" in the
title of every document and to make sure that the title matches
with the document content.

Previously the readme.rst file served as the entrypoint for the
documentation. With a Sphinx build the top-level document is set
to be index.rst as it contains the primary document index.
This patch moves some content from readme.rst into index.rst and
splits the license information out into license.rst.

This change creates the following directories under docs/
in order to provide a grouping for the content:
- components
- design
- getting_started
- perf
- process
In each of these directories an index.rst file is created
and this serves as an index / landing page for each of the
groups when the pages are compiled. Proper layout of the
top-level table of contents relies on this directory/index
structure.
Without this patch it is possible to build the documents
correctly with Sphinx but the output looks messy because
there is no overall hierarchy.

Add the essentials for supporting a Sphinx documentation build:
- A makefile under docs/ to invoke Sphinx with the desired output
format
- A Sphinx master configuration file (conf.py)
- A single, top-level index page (index.rst)
- The TF.org logo that is integrated in the the sidebar of the
rendered output
