92 depends on ARCH_S3C2410 && S3C2410_WATCHDOG
93 help
94 Say y to enable the watchdog during the kernel decompression
95 stage. If the kernel fails to uncompress, then the watchdog
96 will trigger a reset and the system should restart.
97
98 Although this uses the same hardware unit as the kernel watchdog
99 driver, it is not a replacement for it. If you use this option,
100 you will have to use the watchdg driver to either stop the timeout
101 or restart it. If you do not, then your kernel will reboot after
102 startup.
103
104 The driver uses a fixed timeout value, so the exact time till the
105 system resets depends on the value of PCLK. The timeout on an
106 200MHz s3c2410 should be about 30 seconds.

123 to the kernel log, at priority KERN_DEBUG.

152 Set the chunksize in Kilobytes of the CRC for checking memory
153 corruption over suspend and resume. A smaller value will mean that
154 the CRC data block will take more memory, but wil identify any
155 faults with better precision.
