Subject: [PATCHv5 1/2] PCI: layerscape: Add the bar_fixed_64bit property in EP driver.
Date:   Tue, 13 Aug 2019 14:28:39 +0800
Message-Id: <20190813062840.2733-1-xiaowei.bao@nxp.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The PCIe controller of layerscape just have 4 BARs, BAR0 and BAR1
is 32bit, BAR2 and BAR4 is 64bit, this is determined by hardware,
so set the bar_fixed_64bit with 0x14.
