Subject: [PATCH v2 20/22] PCI: layerscape: update PCI config space remap function
Date: Mon, 27 Mar 2017 10:49:48 +0100 [thread overview]
Message-ID: <20170327094954.7162-21-lorenzo.pieralisi@arm.com> (raw)
In-Reply-To: <20170327094954.7162-1-lorenzo.pieralisi@arm.com>
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_ioremap_nopost* interface to make sure the correct
memory mappings for PCI configuration space are used.
