The code was ported from PowerPC and -modified slightly. It has been tested pretty well on PPC on some -rather complex systems with multiple bridges and devices behind -each bridge. However, at the time this README was written, the -mips port was tested only on boards with a single pci bus and -no P2P bridges. It's very possible that on boards with P2P -bridges some modifications have to be made. The code will -evolve, no doubt, but currently every single mips board -is doing its own pcibios thing and it has become a big -mess. This generic pci code is meant to clean up the mips -pci mess and make it easier to add pci support to new boards. - -inside the define for your board in arch/mips/config.in. -For example, the Galileo EV96100 board looks like this: - -if [ "$CONFIG_MIPS_EV96100" = "y" ]; then - define_bool CONFIG_PCI y - define_bool CONFIG_MIPS_GT96100 y - define_bool CONFIG_NEW_PCI y - define_bool CONFIG_SWAP_IO_SPACE y -fi - - -Next, if you want to use the arch/mips/kernel/pci code, which has the -pcibios_init() function, add - -define_bool CONFIG_NEW_PCI y - -inside the define for your board. Again, the EV96100 example above -show NEW_PCI turned on. - - -Now you need to add your files to hook in your pci configuration -cycles. Usually you'll need only a couple of files named something -like pci_fixups.c and pci_ops.c. You can copy the templates -provided and fill in the code. - -The file pci_ops.c should contain the pci configuration cycles routines. -It also has the mips_pci_channels[] array which contains the descriptors -of each pci controller. - -The file pci_fixups.c contains a few routines to do interrupt fixups, -resources fixups, and, if needed, pci bios fixups. - -Usually you'll put your pci_fixups.c file in your board specific directory, -since the functions in that file are board specific. The functions in -pci_ops.c, on the other hand, are usually pci controller specific so that -file could be shared among a few different boards using the same -pci controller. |
