98 bool "S3C2410 Initialisation watchdog"
99 depends on ARCH_S3C2410 && S3C2410_WATCHDOG
100 help
101 Say y to enable the watchdog during the kernel decompression
102 stage. If the kernel fails to uncompress, then the watchdog
103 will trigger a reset and the system should restart.
104
105 Although this uses the same hardware unit as the kernel watchdog
106 driver, it is not a replacement for it. If you use this option,
107 you will have to use the watchdg driver to either stop the timeout
108 or restart it. If you do not, then your kernel will reboot after
109 startup.
110
111 The driver uses a fixed timeout value, so the exact time till the
112 system resets depends on the value of PCLK. The timeout on an
113 200MHz s3c2410 should be about 30 seconds.

130 to the kernel log, at priority KERN_DEBUG.

134 the CPU time doing so.

159 Set the chunksize in Kilobytes of the CRC for checking memory

161 the CRC data block will take more memory, but wil identify any
162 faults with better precision.
