19.1 Enable watchdog

Linux 2.6.25.8 and 2.6.30.4 have watchdog driver. But they still need minor changes.

Modify “drivers/watchdog/s3c2410_wdt.c”£¬line 62 and 63:

#undef S3C_VA_WATCHDOG

#define S3C_VA_WATCHDOG (0)

#include <asm/plat-s3c/regs-watchdog.h>

#define PFX “s3c2410-wdt: ”

#define CONFIG_S3C2410_WATCHDOG_ATBOOT (1) //enable watchdog

#define CONFIG_S3C2410_WATCHDOG_DEFAULT_TIME (30) //set watchdog

static int nowayout = WATCHDOG_NOWAYOUT;

static int tmr_margin = CONFIG_S3C2410_WATCHDOG_DEFAULT_TIME;

static int tmr_atboot= CONFIG_S3C2410_WATCHDOG_ATBOOT;

static int soft_noboot = 0;

static int debug = 0;
