Does anyone know how to find the reason for last reboot on AR71xx and newer?
I'm assuming there is a register somewhere that will tell me if it was
triggered by the hardware watchdog but I'm not finding any info on this
anywhere.

ar71xxreg.h:#define AR71XX_RST_WDOG_CONTROL 0x18060008
ar71xxreg.h:#define RST_WDOG_LAST (1U << 31)
ar71xxreg.h:#define RST_WDOG_ACTION_MASK 3
ar71xxreg.h:#define RST_WDOG_ACTION_RESET 3
ar71xxreg.h:#define RST_WDOG_ACTION_NMI 2
ar71xxreg.h:#define RST_WDOG_ACTION_GP_INTR 1
ar71xxreg.h:#define RST_WDOG_ACTION_NOACTION 0
.. I think if RST_WDOG_LAST=1, then it was last rebooted by the watchdog.
