+ * @todo Rename; perhaps "debug_driver".  This isn't an interface,
+ * it's a driver!  Also, not all drivers support JTAG.
+ *
+ * @todo We need a per-instance structure too, and changes to pass
+ * that structure to the driver.  Instances can for example be in
+ * either SWD or JTAG modes.  This will help remove globals, and
+ * eventually to cope with systems which have more than one such
+ * debugging interface.
