Hi, I am currently writing a driver for a PCIe host controller which does not support IO port access. My plan was to only provide IORESOURCE_MEM to pci_sys_data->resources, but then it allocates some generic IORESOURCE_IO memory in arch/arm/kernel/bios32.c:pcibios_init_resources(). This will work for the fist PCIe controller, but when the second controller gets registered I am getting this: "unable to allocate I/O port region (-16)". Is there an example for an arm driver for a PCIe controller which does not support IO port access? Should I change arch/arm/kernel/bios32.c in a way so that it would ignore the io port mem?
