doc: mkimage: Further document -o and -R
Despite the original description of these options, they are not always image names, or even files. Some image types use these options to convey configuration directly. Re-document these options as configuration options. Additionally, add a new section documenting the format of the configuration for each image type which uses it. In general, if configuration is used directly (without a separate file) I have added documentation for it. If the configuration points to a separate file, I have referenced that file's documentation. Where there is no such documentation, I have added it. Signed-off-by: Sean Anderson <seanga2@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
