mkimage: Display a better list of available image types
Offer to display the available image types in help. Also, rather than hacking the genimg_get_type_id() function to display a list of types, do this in the tool. Also, sort the list. The list of image types is quite long, and hard to discover. Print it out when we show help information. Signed-off-by: Simon Glass <sjg@chromium.org>
