    Sanitise includes across codebase · 09d40e0e

    Enforce full include path for includes. Deprecate old paths.
    The following folders inside include/lib have been left unchanged:
    - include/lib/cpus/${ARCH}
    - include/lib/el3_runtime/${ARCH}
    The reason for this change is that having a global namespace for
    includes isn't a good idea. It defeats one of the advantages of having
    folders and it introduces problems that are sometimes subtle (because
    you may not know the header you are actually including if there are two
    of them).
    For example, this patch had to be created because two headers were
    called the same way: e0ea0928 ("Fix gpio includes of mt8173 platform
    to avoid collision."). More recently, this patch has had similar
    problems: 46f9b2c3 ("drivers: add tzc380 support").
    This problem was introduced in commit 4ecca339 ("Move include and
    source files to logical locations"). At that time, there weren't too
    many headers so it wasn't a real issue. However, time has shown that
    this creates problems.
    Platforms that want to preserve the way they include headers may add the
    removed paths to PLAT_INCLUDES, but this is discouraged.
