It won't do anything, though, unless it finds a node that matches 
of_default_bus_ids.  Are there any platforms on which "soc" nodes (or 
others in the default list) shouldn't be probed?  If not, perhaps make a 
generic initcall to of_platform_bus_probe(), so that it won't be called 
multiple times by different SoC types that are in the same kernel?

Otherwise, perhaps the SoCs could be given "fsl-soc" in their compatible 
field, and have fsl_publish_devices() pass that as a match struct.

It's not really a board-level issue, though -- at most, it's SoC-level.
