Hm... it is one of the basic design principles of U-Boot to provide debug output on the console as soon as possible. It should be the primary purpose of low level initialization to enable console output, before anything else. Now you say, you have output even before that - this aears to be a contradiction to me. If you can output characters, then use this as your console. I feel we should not need any special configuration options to do what we should do anyway. Or am I missing somthing?
