From 01bd489dba01bcc58b23c669b437330039639c75 Mon Sep 17 00:00:00 2001 From: Lorenzo Pieralisi Date: Wed, 19 Apr 2017 17:49:08 +0100 Subject: [PATCH] PCI: layerscape: Update PCI config space remap function PCI configuration space should be mapped with a memory region type that generates on the CPU host bus non-posted write transations. Update the driver to use the devm_pci_remap_cfg* interface to make sure the correct memory mappings for PCI configuration space are used.
