Devicetree dependency is already covered with #ifdef CONFIG_OF. Problem is
that it really needs #ifdef CONFIG_OF_ADDRESS. Though even that might be
better than my patch, since it would at least build the driver on sparc
as it used to do.

No idea, sorry. Can you by any chance use pcie device information
instead of depending on devicetree data ?
