Arnd Bergmann 9b0f7e3992 arm: versatile: fix and enable PCI I/O space ... With commit 4d5fc58dbe (ARM: remove bunch of now unused mach/io.h files), the I/O space setup was completely broken on versatile. This patch fixes that and prepares for further I/O space clean-up. I/O space handling on the versatile platform is currently broken in multiple ways. Most importantly, the ports do not get mapped into the virtual address space at all. Also, there is some amount of confusion between PCI I/O space and other statically mapped MMIO registers in the platform code: * The __io_address() macro that is used to access the platform register maps to the same __io macro that gets used for I/O space. * The IO_SPACE_LIMIT is set to a value that is much larger than the total available space. * The I/O resource of the PCI bus is set to the physical address of the mapping, which is way outside of the actual I/O space limit as well as the address range that gets decoded by traditional PCI cards. * No attempt is made to stay outside of the ISA port range that some device drivers try access. * No resource gets requested as a child of ioport_resource, but an IORESOURCE_IO type mapping gets requested as a child of iomem_resource. This patch attempts to correct all of the above. This makes it possible to use virtio-pci based virtual devices as well as actual PCI cards including those with legacy ISA port ranges like VGA. Some of the issues seem to be duplicated on other platforms.
