      Add support for Branch Target Identification · 9fc59639
      Alexei Fedorov authored
      This patch adds the functionality needed for platforms to provide
      Branch Target Identification (BTI) extension, introduced to AArch64
      in Armv8.5-A by adding BTI instruction used to mark valid targets
      for indirect branches. The patch sets new GP bit [50] to the stage 1
      Translation Table Block and Page entries to denote guarded EL3 code
      pages which will cause processor to trap instructions in protected
      pages trying to perform an indirect branch to any instruction other
      than BTI.
      BTI feature is selected by BRANCH_PROTECTION option which supersedes
      the previous ENABLE_PAUTH used for Armv8.3-A Pointer Authentication
      and is disabled by default. Enabling BTI requires compiler support
      and was tested with GCC versions 9.0.0, 9.0.1 and 10.0.0.
      The assembly macros and helpers are modified to accommodate the BTI
      This is an experimental feature.
      Note. The previous ENABLE_PAUTH build option to enable PAuth in EL3
      is now made as an internal flag and BRANCH_PROTECTION flag should be
      used instead to enable Pointer Authentication.
      Note. USE_LIBROM=1 option is currently not supported.

      doc: Use proper note and warning annotations · e1c5026a
      Paul Beesley authored
      The documentation contains plenty of notes and warnings. Enable
      special rendering of these blocks by converting the note prefix
      into a .. note:: annotation.

      - Make the list of contributors into an actual list
      - Use note syntax for the note
      - Remove the Individuals heading since there are none
      This file could be considered for removal as it is a legacy
      document, as its note explains.

      doc: Set correct syntax highlighting style · 29c02529
      Paul Beesley authored
      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.

      doc: Add minimal glossary · 8f62ca7b
      Paul Beesley authored
      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.

      doc: Remove per-page contents lists · 57354abb
      Paul Beesley authored
      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.

      The platform port documents are not very standardised right now and
      they don't integrate properly into the document tree so:
      1) Make sure each port has a proper name and title (incl. owner)
      2) Correct use of headings, subheadings, etc in each port
      3) Resolve any naming conflicts between documents

      doc: Reword document titles · 8aa05055
      Paul Beesley authored
      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.
