2019-10-11doc: Misc syntax and spelling fixesPaul Beesley
Tidying up a few Sphinx warnings that had built-up over time. None of these are critical but it cleans up the Sphinx output. At the same time, fixing some spelling errors that were detected. Change-Id: I38209e235481eed287f8008c6de9dedd6b12ab2e Signed-off-by: Paul Beesley <paul.beesley@arm.com>
2019-10-08doc: Convert internal links to RST formatPaul Beesley
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.

2019-07-22Romlib makefile refactoring and script rewritingImre Kis
The features of the previously existing gentbl, genvar and genwrappers scripts were reimplemented in the romlib_generator.py Python script. This resulted in more readable and maintainable code and the script introduces additional features that help dependency handling in makefiles. The assembly templates were separated from the script logic and were collected in the 'templates' directory. The targets and their dependencies were reorganized in the makefile and the dependency handling of included index files is possible now. Incremental build is available in case of modifying the index files. Signed-off-by: Imre Kis <imre.kis@arm.com> Change-Id: I79f65fab9dc5c70d1f6fc8f57b2a3009bf842dc5
2019-07-12doc: Generate PlantUML diagrams automaticallyPaul Beesley
Currently we have some pre-rendered versions of certain diagrams in SVG format. These diagrams have corresponding PlantUML source that can be rendered automatically as part of the documentation build, removing the need for any intermediate files. This patch adds the Sphinx "plantuml" extension, replaces references to the pre-rendered SVG files within the documents, and finally removes the SVG files and helper script. New requirements for building the docs are the "sphinxcontrib-plantuml" Python module (added to the pip requirements.txt file) and the Graphviz package (provides the "dot" binary) which is in the Ubuntu package repositories.

2019-07-10Remove references to old project name from common filesJohn Tsichritzis
The project has been renamed from "Arm Trusted Firmware (ATF)" to "Trusted Firmware-A (TF-A)" long ago. A few references to the old project name that still remained in various places have now been removed. This change doesn't affect any platform files. Any "ATF" references inside platform files, still remain. Change-Id: Id97895faa5b1845e851d4d50f5750de7a55bf99e Signed-off-by: John Tsichritzis <john.tsichritzis@arm.com>

2019-05-22doc: Use proper note and warning annotationsPaul Beesley
The documentation contains plenty of notes and warnings. Enable special rendering of these blocks by converting the note prefix into a .. note:: annotation. Change-Id: I34e26ca6bf313d335672ab6c2645741900338822 Signed-off-by: Paul Beesley <paul.beesley@arm.com>

2019-05-22doc: Set correct syntax highlighting stylePaul Beesley
Several code blocks do not specify a language for syntax highlighting. This results in Sphinx using a default highlighter which is Python. This patch adds the correct language to each code block that doesn't already specify it. Change-Id: Icce1949aabfdc11a334a42d49edf55fa673cddc3 Signed-off-by: Paul Beesley <paul.beesley@arm.com>
2019-05-22doc: Add minimal glossaryPaul Beesley
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.

2019-05-22doc: Remove per-page contents listsPaul Beesley
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.

2019-05-22doc: Reword document titlesPaul Beesley
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.

2019-05-21doc: Move documents into subdirectoriesPaul Beesley
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.
