On the Armada-38x platforms (and probably 37x/XP) the current behaviour of on exipry of the watchdog is a silent reboot of the CPU. The Armada-38x does have an interrupt which if we don't enable the Global WD bit in the RSTOUTn register gives us a chance to generate some panic messages that may help track down the cause of the watchdog timeout.
I've been a bit bold and enabled this in the generic armada-38x.dtsi file. I'd be happy to leave that part out and have the interrupt enabled on a board-by-board basis if there are objections.
