From 458a83fa43e83505f9401783ce9ed41b5a8b5591 Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Fri, 29 Apr 2005 21:58:16 +0100 Subject: [PATCH] [PATCH] ARM: 2659/1: do not assign PCI I/O address zero on IXP2000 Patch from Lennert Buytenhek Assigning the address zero to a PCI device BAR causes some part of the PCI subsystem to believe that resource allocation for that BAR failed due to resource conflicts, which will make attempts to enable the device fail. Work around this by assigning I/O addresses starting from 00010000. While we're at it, make the PCI I/O resource end at 0001ffff, since we only have 64k of outbound I/O window on the IXP2000, and we don't do bank switching.
