David B. Kinder 2cb045420c doc: fix .rst files canonical heading order The headings on some .rst files were not following the expected heading order of using # for h1, * for h2, = for h3, and - for h4 This patch fixes that, and the doc/templates/*.tmpl files created for folks to use as templates for creating board and sample docs.
