This causes troubles for [1], but I have no clue yet, what is happening. Without the patch, we start like this:

Obviously, the DT target adress changed, possibly to an unsupported/reserved address. But I do not understand the mechanics behind all this yet. Any hints welcome on what goes wrong here and whether something needs to be adjusted in our board settings.
Can you share the output of bdinfo on this board ?
