Menus are composed of items. Each item has a key used to identify it in
the menu, and an opaque pointer to data controlled by the consumer.
+If you want to show a menu, instead of starting the shell, define
+CONFIG_MENU_SHOW. You have to code the int menu_show(int bootdelay)
+function, which handles your menu. This function returns the remaining
+bootdelay.
