From 4663f45caa2352760ee08ec28b9c2d6e2e8823f9 Mon Sep 17 00:00:00 2001 From: Kyösti Mälkki Date: Thu, 7 Mar 2019 14:18:28 +0200 Subject: device/pci_ops: Have only default PCI bus ops available MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In the current state of the tree we do not utilise the mechanism of having per-device overrides for PCI bus ops. This change effectively inlines all PCI config accessors for ramstage as well.
