Add this test to the documentation. We need to move the import to follow the main comment so that it renders correctly, and add a code-block annotation to the example and indent it correctly. Next, neither of the functions had comments themselves, so document them now. Signed-off-by: Tom Rini <trini@konsulko.com> Reviewed-by: Simon Glass <sjg@chromium.org>
