From d79e743e9fcf03f521300a970eb1ab69641910ba Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Wed, 21 Sep 2005 14:14:22 +1000 Subject: [PATCH] [PATCH] ppc64: Fix PCI flags when using OF device tree My code to set up the PCI tree from the Open Firmware device tree was setting IORESOURCE_* flags on the resources for the devices, but not the PCI_BASE_ADDRESS_* flags. This meant that some drivers misbehaved, and /proc/pci showed the wrong types for the resources. This fixes it.
