Then its probably just a matter of whoever configures the kernel needs
to know what version of IP is being used.  ie. always have the
fallback of compile time specification of IP version. Could be done
manually, or by putting the info into the dts.  We probably need a
tool to generate a dts from the .mhs or xparameters.h file anyway.
