I guess I cannot apply this to my networking tree then.

I would suggest that you make a helper in a header file which dos the
special SMC EMAC accesses, or alternatively the regular regmap access,
based upon the CPP ifdef.

That way you won't have to put all of those CPP tests in the foo.c
code.

Thanks.
