From b83858af5b29ef468f732591269ce7eb471d7591 Mon Sep 17 00:00:00 2001 From: Mario Scheithauer Date: Tue, 5 Sep 2017 15:32:49 +0200 Subject: siemens/mc_apl1: Set bus master bit for on-board PCI device There is one on-board PCI device where bus master has to be enabled in PCI configuration space. As there is no need for a complete PCI driver for this device just set the bus master bit in mainboard_final().
