121 bool "S3C2410 Initialisation watchdog"
122 depends on ARCH_S3C2410 && S3C2410_WATCHDOG
123 help
124 Say y to enable the watchdog during the kernel decompression
125 stage. If the kernel fails to uncompress, then the watchdog
126 will trigger a reset and the system should restart.
127
128 Although this uses the same hardware unit as the kernel watchdog
129 driver, it is not a replacement for it. If you use this option,
130 you will have to use the watchdg driver to either stop the timeout
131 or restart it. If you do not, then your kernel will reboot after
132 startup.
133
134 The driver uses a fixed timeout value, so the exact time till the
135 system resets depends on the value of PCLK. The timeout on an
136 200MHz s3c2410 should be about 30 seconds.
