 230
 231           Although this uses the same hardware unit as the kernel watchdog
 232           driver, it is not a replacement for it. If you use this option,
 233           you will have to use the watchdg driver to either stop the timeout
 234           or restart it. If you do not, then your kernel will reboot after
 235           startup.
 236
 237           The driver uses a fixed timeout value, so the exact time till the
 238           system resets depends on the value of PCLK. The timeout on an
 239           200MHz s3c2410 should be about 30 seconds.
