 It may be useful to force-enable the watchdog in the buildroot config
it this option is selected.  For me, that's not necessary though.

 It would look something like this:

ifeq ($(BR2_PACKAGE_BUSYBOX_WATCHDOG),y)
define BUSYBOX_SET_WATCHDOG
        $(call KCONFIG_ENABLE_OPT,CONFIG_WATCHDOG,$(BUSYBOX_BUILD_CONFIG))
endef
endif

and then add BUSYBOX_SET_WATCHDOG to the rest of the config modifiers.


 Regards,
 Arnout
