I'm slightly confused about this property - is this covering differences
in the IP deployed on different SoCs or is it covering how the SoC is
wired into the board?  If it's for how the SoC is wired into the board
(ie, Rx and Tx wired together) then this should already be covered by
either the machine driver or the device at the other end of the link.
