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? - kumar
