From cdfb46240b4bba8a112c85a5f5d26447e90378b3 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ky=C3=B6sti=20M=C3=A4lkki?= Date: Tue, 22 Jul 2014 15:24:15 +0300 Subject: AGESA boards: Use devicetree for PCI bus enumeration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Previously MP table contained PCI_INT entries for PCI bus behind bridge 0:14.4 even if said PCI bridge function was disabled. Remove these as invalid, indeterminate bus number could cause conflicts. PCI_INT entries with bus_sb800[2], bus_hudson[2] and bus_yangtze[2] were invalid as there is no PCI bridge hardware on device 0:14.0. Remove these as invalid, indeterminate bus number could cause conflicts.
