-Subject: [PATCH 1/2] PCI: BCM5301X: add PCIe2 driver for BCM5301X SoCs
-
-This driver supports the PCIe controller found on the BCM4708 and
-similar SoCs. The controller itself is automatically detected by bcma.
-
-This controller is found on SoCs usually used in SOHO routers to
-connect the wifi cards to the SoC. 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. I have
-to remove the call to pci_bus_add_devices() in pci_scan_root_bus() to
-make registration work, calling pci_bus_add_devices() later again does
-not fix this problem.
