I'd like to enable the watchdog in u-boot and then have it still enabled once I boot into linux. The motivation is that I want to make sure the kernel comes up ok.
I can enable the watchdog and see it reset in uboot just fine with manual register writes

but once I boot into linux it doesn't seem to reboot and I don't think there is anything that is servicing it because I can manually enable in linux and watch it reboot
echo "1" > /dev/watchdog0
