Hi, Trying to change PCI IO window base for 52xx target I found that we are pretty much limited to a "0" offset only.
pci_process_bridge_OF_ranges() will not process any IO range that has addresses set to anything else. 956: case 1: /* I/O space */ 957: if (ranges[2] != 0) 958: break; When this range[2] checking is removed from pci_process_bridge_OF_ranges() kernel boots ok with the non-zero PCI IO base, but the PCI device I am using (e100) will not work. I guess that with the above dropping of non-zero based PCI IO ranges this is not supposed to be working. But does anyone know why?
