> In current implementation, any exception would trigger a CPU reset.
> But a bad written SPL would cause infinite loop where the system will reload
> the same SPL instead of loading factory safe image.
> 
> Hence this patch is to ensure any exception will cause a hang. At this
> moment, watchdog shall be triggered and Remote System Update
> mechanism shall load the next production image or factory safe image.
