See patch. Will post a patch for changing the port on SB700 soon, on that southbridge it is indeed possible according to the datasheet.

AMD SB600 uses a hardcoded USB Debug Port number. It cannot be changed via software according to the datasheet, whereas this is indeed possible on AMD SB700. I tested using the SB700 mechanism on SB600 but it didn't work, so I suspect the datasheet is indeed correct. Thus, don't show the kconfig option for selecting the physical USB port on the AMD SB600 southbridge.
