From 42a83765d54f042b4079e05a3438789542429981 Mon Sep 17 00:00:00 2001 From: Richard Retanubun Date: Fri, 20 Mar 2009 15:30:10 -0400 Subject: Adds WATCHDOG_RESET() function call to lib_m68k dtimer_interrupt. Ported from lib_ppc/interrupts.c, this adds the ability for the coldfire system timer to auto-reset the watchdog when dtimer_interrupts is called.
