检测是否关机充电的时候，带入如下参数：

#ifdef MTK_KERNEL_POWER_OFF_CHARGING
if(kernel_power_off_charging_detection(g_battery_cust))
{
printf(" < Kernel Power Off Charging Detection Ok> \n");
return;
}
else
{
printf("< Kernel Enter Normal Boot > \n");
}
#endif

检测中做如下动作：
BOOL kernel_power_off_charging_detection(int g_battery_cust)
{
#if 0
if((upmu_is_chr_det() == KAL_TRUE))
{
if(bypass_kernel_power_off_charging()){
return FALSE;
}
else
{

g_boot_mode = KERNEL_POWER_OFF_CHARGING_BOOT;
return TRUE;
}
}
else
{
upmu_set_rg_chrind_on(0);
printf("[%s] Turn off HW Led\n", __func__);
return FALSE;
}
#else
/* */
if(is_force_boot()) {
      upmu_set_rg_chrind_on(0);
printf("[%s] Turn off HW Led\n", __func__);
      return FALSE;
}

if((upmu_is_chr_det() == KAL_TRUE)) {
      g_boot_mode = KERNEL_POWER_OFF_CHARGING_BOOT;
//zcfdebug++<<
if(g_battery_cust == 0){
//这里会导致无限重启       printf("[kernel_power_off_charging_detection] no battery and then power off\n");
//       mt6575_power_off();
return FALSE;
}
//zcfdebug>>++
return TRUE;
}
else {
      /* power off */
      #ifndef NO_POWER_OFF
      printf("[kernel_power_off_charging_detection] power off\n");
      mt6575_power_off();
      #endif
return FALSE;
}
/* */
#endif
}
