- * Menu option types.
- * There are a number of different layouts for menu options depending
- * on their types. Currently there are the following possibilities:
- *
- * Submenu:
- * This entry links to a new menu.
- *
- * Boolean:
- * A simple on/off toggle entry. Booleans can be either yes/no, 0/1 or on/off.
- * Optionally, this entry can enable/disable a set of other options. An example would
- * be to enable/disable on-board USB, and if enabled give access to further options like
- * irq settings, base address etc.
- *
- * Text:
- * A single line/limited number of characters text entry box. Text can be restricted
- * to a certain charset (digits/hex digits/all/custom). Result is also available as an
- * int if numeric.
- *
- * Selection:
- * One-of-many type of selection entry. User may choose on of a set of strings, which
- * maps to a specific value for the variable.
- *
- * Routine:
- * Selecting this calls an entry-specific routine. This can be used for saving contents etc.
- *
- * Custom:
- * Display and behaviour of this entry is defined by a set of callbacks.
