- help
- Say y to enable the watchdog during the kernel decompression
- stage. If the kernel fails to uncompress, then the watchdog
- 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.
