No, we do not have this atm. Are you looking for real watchdog support, i.e. 'reset watchdog when my system is in a sane state' or do you have a piece of hardware on which you have to reset the watchdog frequently because you can't disable it in software? For the first case I propose a 'watchdog' command with an underlying reset_watchdog() function which resets the watchdog. For the latter case you don't have another choice but to scatter the code with RESET_WATCHDOG macros like U-Boot does.
