-/* RIO uses the NatSemi Super I/O power management logical device
- * as its' watchdog.
- *
- * When the watchdog triggers, it asserts a line to the BBC (Boot Bus
- * Controller) of the machine. The BBC can only be configured to
- * trigger a power-on reset when the signal is asserted. The BBC
- * can be configured to ignore the signal entirely as well.
- *
- * The only Super I/O device register we care about is at index
- * 0x05 (WDTO_INDEX) which is the watchdog time-out in minutes (1-255).
- * If set to zero, this disables the watchdog. When set, the system
- * must periodically (before watchdog expires) clear (set to zero) and
- * re-set the watchdog else it will trigger.
- *
- * There are two other indexed watchdog registers inside this Super I/O
- * logical device, but they are unused. The first, at index 0x06 is
- * the watchdog control and can be used to make the watchdog timer re-set
- * when the PS/2 mouse or serial lines show activity. The second, at
- * index 0x07 is merely a sampling of the line from the watchdog to the
- * BBC.
- *
- * The watchdog device generates no interrupts.
