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