4 bool "Enable U-Boot watchdog reset"
5 depends on !HW_WATCHDOG
7 This option enables U-Boot watchdog support where U-Boot is using
8 watchdog_reset function to service watchdog device in U-Boot. Enable

21 would be able to start watchdog manually by 'wdt' command. Useful
22 when you want to have support for 'wdt' command but do not want
23 to have watchdog enabled by default.
