From 0c797f1c28cd16c64482b2cea554e89baaa31445 Mon Sep 17 00:00:00 2001 From: Kyösti Mälkki Date: Mon, 21 Jul 2014 19:35:16 +0300 Subject: AGESA: Drop offset on PCI device enumeration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Integrated PCI devices in southbridge silicon have static BDFs, no need to have variables to store the parent bus or an offset with constant zero.
