Hi, This is a set of experimental patches that allow ARM PCI host drivers to be unloaded. The first two patches enhance the ARM core PCI code with functions to tear down fixed PCI I/O mappings and unregister a PCI host bridge. The third patch uses the new functionality to allow the Tegra PCIe driver to unbind from a device. I'm sending this as an RFC because, while I've been able to successfully unbind and rebind the Tegra PCIe driver and verifying that a NIC connected via PCIe still works after each new probe, I haven't fully investigated yet whether there may be memory leaks due to missing cleanup.
