From cd00f084ed1d501c8cb391c6d98b4f31b2a9a3e2 Mon Sep 17 00:00:00 2001 From: Lorenzo Pieralisi Date: Wed, 19 Apr 2017 17:48:58 +0100 Subject: [PATCH] PCI: xilinx-nwl: 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.
