+ Automatically start watchdog timer and start servicing it during
+ init phase. Enabled by default. Disable this option if you want
+ to compile U-Boot with CONFIG_WDT support but do not want to
+ activate watchdog, like when CONFIG_WDT option is disabled. You
+ would be able to start watchdog manually by 'wdt' command. Useful
+ when you want to have support for 'wdt' command but do not want
