From 96d69c31c5115341c6c1163aa3d591c2da687a76 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Sat, 12 Jan 2008 17:23:26 -0600 Subject: [PATCH] [POWERPC] Ensure we only handle PowerMac PCI bus fixup for memory resources The fixup code that handles the case for PowerMac's that leave bridge windows open over an inaccessible region should only be applied to memory resources (IORESOURCE_MEM). If not we can get it trying to fixup IORESOURCE_IO on some systems since the other conditions that are used to detect the case can easily match for IORESOURCE_IO.
