How far are you progressed? On quick reading the changes needed, the path I see before me now is to first make the endianness configuable at runtime for all relevant devices, then implement the new configuration/arbiter stuff but at first negotiate/demand the classic setup as much as needed and as last go over each driver and make them more flexible where needed.
