I'd like the SWIOTLB refactoring as a separate patch. Additionally, the order of patches should be as follows: 1. refactor PCI node parsing code 2. add pci_determine_swiotlb (should rename to fsl_pci_determine_swiotlb) 3. Determine primary bus by looking for ISA node 4. convert all boards over to fsl_pci_init 5. convert fsl pci to platform driver (edac and other fixes should be merged in here) 6.
