Thanks to the efforts of Michael Karcher, we have a clean room reverse engineered doc for the flashing interface, and Carl-Daniel Hailfinger has integrated a patch that supports read and write on most boards. There is no further development at the moment, but we are happy about verbose logs of any board that does (not) work and is not already mentioned at Supported hardware.
