hw/arm/stellaris: Implement watchdog timer
Implement the watchdog timer for the stellaris boards. This device is a close variant of the CMSDK APB watchdog device, so we can model it by subclassing that device and tweaking the behaviour of some of its registers. Signed-off-by: Michel Heily <michelheily@gmail.com> Reviewed-by: Peter Maydell <petser.maydell@linaro.org> [PMM: rewrote commit message, fixed a few checkpatch nits, added comment giving the URL of the spec for the Stellaris variant of the watchdog device] Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
