[U-Boot] hw_watchdog

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.
