    So the SDMA actually switch and twist around the endianness of
    its registers if it's synthesized into a bigendian version of the system?

    Or hardware-dynamically even depending on the setting of the
    endianness bit in the ARM core?

    How can that possibly even work...

    But I'm still impressed by the statemachines some silicon
    engineers come up with so wouldn't surprise me. X-)
    I understand the code now atleast. Our hardware is always
    synthesized LE so we so handily use [read|write][b|w|l]
    everywhere, luckily.
