    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.
