 235
 236           Although this uses the same hardware unit as the kernel watchdog
 237           driver, it is not a replacement for it. If you use this option,
 238           you will have to use the watchdg driver to either stop the timeout
 239           or restart it. If you do not, then your kernel will reboot after
 240           startup.
 241
 242           The driver uses a fixed timeout value, so the exact time till the
 243           system resets depends on the value of PCLK. The timeout on an
 244           200MHz s3c2410 should be about 30 seconds.
