[U-Boot] hw_watchdog

[andrew@PolkaSpots.com]

How can I find out if hw_watchdog is enabled on my U-Boot?
Is there a timing variable that I need to set in "u-boot-env"
Or that part of the code is executed earlier.

Bassically what im experienceing is that sometimes, in some unknown 
conditions, U-Boot will freeze, at the point when is relocating to RAM. 
I belive.
O dont get anything else after DRAM:  64 M.

Kernel which I'm using is 3.10.
Any advice will be very much appreciated.

Thanks.
