From 7f1913938984ef6c6a46cb53e003719196d9c5de Mon Sep 17 00:00:00 2001 From: Grzegorz Bernacki Date: Fri, 7 Sep 2007 18:20:23 +0200 Subject: [PPC440SPe] Improve PCIe configuration space access - correct configuration space mapping - correct bus numbering - better access to config space Prior to this patch, the 440SPe host/PCIe bridge was able to configure only the first device on the first bus. We now allow to configure up to 16 buses; also, scanning for devices behind the PCIe-PCIe bridge is supported, so peripheral devices farther in hierarchy can be identified.
