I am not sure I understand you right, but Non-nor deep sleep support is more than just disabling console. We need to update board head file, like t102xqds.h, as well. I think you are right. We should add non-nor boot support. Please apply these patches. I will send another two patch to support QDS non-nor boot deep sleep on qds.
