	help
	  Say y to enable the watchdog during the kernel decompression

	  will trigger a reset and the system should restart.

	  Although this uses the same hardware unit as the kernel watchdog
	  driver, it is not a replacement for it. If you use this option,
	  you will have to use the watchdg driver to either stop the timeout
	  or restart it. If you do not, then your kernel will reboot after
	  startup.

	  The driver uses a fixed timeout value, so the exact time till the
	  system resets depends on the value of PCLK. The timeout on an
	  200MHz s3c2410 should be about 30 seconds.
