 113
 114           Although this uses the same hardware unit as the kernel watchdog
 115           driver, it is not a replacement for it. If you use this option,
 116           you will have to use the watchdg driver to either stop the timeout
 117           or restart it. If you do not, then your kernel will reboot after
 118           startup.
 119
 120           The driver uses a fixed timeout value, so the exact time till the
 121           system resets depends on the value of PCLK. The timeout on an
 122           200MHz s3c2410 should be about 30 seconds.
