 120
 121           Although this uses the same hardware unit as the kernel watchdog
 122           driver, it is not a replacement for it. If you use this option,
 123           you will have to use the watchdg driver to either stop the timeout
 124           or restart it. If you do not, then your kernel will reboot after
 125           startup.
 126
 127           The driver uses a fixed timeout value, so the exact time till the
 128           system resets depends on the value of PCLK. The timeout on an
 129           200MHz s3c2410 should be about 30 seconds.
