The watchdog driver probes all available watchdog devices. This causes SMP boot errors when bringing up secondary CPUs. In our setup, only a single watchdog is needed to monitor the boot process until userspace or the OS takes over. Disable all unnecessary watchdog devices in U-Boot to avoid conflicts during CPU bring-up.
