Use the same 'itl' (for image-tool) whenever this parameter is passed around. This makes it easier to recognise. Move away from using the word 'parameters', since it contains essentially all of the info about the tool, not just parameters. Use 'info' instead. Signed-off-by: Simon Glass <sjg@chromium.org>
