     Imx6q linux 3.0.35

     Switch boot config to sd3, as kernel is loaded from sd3 and then change boot config to sd4, reboot system, the  system      load from sd3 again.

     Why does not bootrom  update boot cofig status? 

     If provide POR_B pin  reset sequence, the same result as uper description.
