Yes, but that essentially means replacing it with a file that only provides trivial implementations for pcibios_fixup_bus(), pcibios_align_resource(), and pcibios_add_device(). I don't think you need any others. > From the sentence (or putting it under and Kconfig symbol initially) you > mean to say (putting it under arm Kconfig symbol). Sorry for being unclear. I meant putting the current implementation under a new microblaze specific Kconfig symbol so you can use it with the original host driver implementation as an alternative to the new new implementation. Once you have migrated to the new code it can be deleted. Arnd
