From 34fb95494f01cd0adbcfae5d113f669336d8cf0c Mon Sep 17 00:00:00 2001

Subject: [PATCH 2/3] init-install-efi/SWU: add setup WDT routine to enable if
mel_wdt is 1
> set WDT timeout to 60s by default to reboot in case system hangs.
> start WDT ONLY IF mel_wdt is set to 1.
>> this allows user to disable the WDT in case the user is doing
kernel debugging or so and wants the system to keep running.
> enable WDT (set mel_wdt=1) by default
