-This README briefly explains how to use the pci and pci_auto
-code in arch/mips/kernel.  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.
