Ok, I'm asked and I'm answering!  :)

 

I found driver source file of watchdog, and comment the line which spammed to message file.

 

Here it is: pr_info("%s, write reg 0x%08x\n", __func__, (u32)&wdt_reg->ctrl);

static int wdt_restart(void)
{
#ifdef WATCHDOG_DBG
    if(NULL == wdt_reg) {
        pr_err("%s err, line %d\n", __func__, __LINE__);
        return -1;
    }
#endif

    //pr_info("%s, write reg 0x%08x\n", __func__, (u32)&wdt_reg->ctrl);
    writel((0xA57 << 1) | (1 << 0), &wdt_reg->ctrl);
    return 0;
}

I recompiled the core and the problem solved. 

 

I hope this information will be taken into consideration when creating new system images...  :rolleyes:
