I am not a fan of enabling something that is a SoC feature on only one
of the boards that I maintain, especially when ODROID-M1 is part of
same/similar board family.

Maybe we could add a WDT config fragment and imply DESIGNWARE_WATCHDOG
at SoC (or arch) level. At the very least, please extend this to include
both M1 and M1S.

Regards,
Jonas
