What do you plan on doing with the local bus controller in the kernel?  
If this is only configuration of the controller for a given chip select 
that I would suggest doing something similar to how we handle PCI.  You 
can probably find a description of the localbus registers in the u-boot 
source tree.

Is this a change you want to get back into the mainline kernel tree?
