The following timers (same as the timers on OMAP4 Panda boards) are used as the watchdog timers, DSP : GPT6 IPU : GPT9 & GPT11 (one for each Cortex-M4 core) The MPU-side drivers will use this data to initialize the watchdog timers, and listen for any watchdog triggers. The BIOS-side code needs to configure and refresh these timers properly to not throw a watchdog error. These timers can be changed or removed as per the system integration needs, alongside appropriate equivalent changes on the firmware side.
