From 3fd47f063b17692e843128e2abda3e697df42198 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Mon, 6 May 2013 13:40:40 +1000 Subject: powerpc/pci: Support per-aperture memory offset The PCI core supports an offset per aperture nowadays but our arch code still has a single offset per host bridge representing the difference betwen CPU memory addresses and PCI MMIO addresses. This is a problem as new machines and hypervisor versions are coming out where the 64-bit windows will have a different offset (basically mapped 1:1) from the 32-bit windows. This fixes it by using separate offsets. In the long run, we probably want to get rid of that intermediary struct pci_controller and have those directly stored into the pci_host_bridge as they are parsed but this will be a more invasive change.
