The PCI support for the Integrator AP has apparently never been finished and I strongly suspect that it has never worked, so let's fix it. This is a list of the more or less un-splittable changes done in this driver rewrite: - Replace the register definitions stashed into the config file (!) with a copy if the register file from the Linux kernels arch/arm/include/asm/hardware/pci_v3.h - Delete the unreadable gigantic macros that perform the config accesses and replace them with copyedited code from Linux arch/arm/mach-integrator/pci_v3.c - Rewrite the rest of the setup code to use the v3_[read|write][lwb]() accessors. - Enable PCI by default in the AP board configuration. - Fix checkpatch warnings and make code more conformant.
