    Most of these use a sample .dts file to build an image and then check
    that it looks correct. The sample files are in the test/ subdirectory
    and are numbered.

    For each entry type a very small test file is created using fixed
    string contents. This makes it easy to test that things look right, and
    debug problems.

    In some cases a 'real' file must be used - these are also supplied in
    the test/ diurectory.
