All the of the BCM5301X SoCs I know +of have 2 or 3 of these controllers in the SoC. + +I had to use PCI domains otherwise the pci_create_root_bus() function +in drivers/pci/probe.c would fail for the second controller being +registered because pci_find_bus() would find the same PCIe bus again +and assume it is already registered, which ends up in a kernel panic in +pcibios_init_hw() in arch/arm/kernel/bios32.c + +The ARM PCI code assumes that every controller has an I/O space and +adds a dummy area if the driver does not specify one. This will work +for the first controller, but when we register the second one this will +result in an error. To prevent this problem we add an empty I/O space. + +Currently I have problems with probing the devices on the bus, because +pci_bus_add_devices() is called too early in pci_scan_root_bus() in +drivers/pci/probe.c, before pci_bus_assign_resources() was called in +pci_common_init_dev() in arch/arm/kernel/bios32.c. When the devices are +added too early they do not have any resources and adding fails.
