Subject: [PATCHv3 1/2] PCI: layerscape: Add the bar_fixed_64bit property in EP driver.
Date: Fri, 28 Jun 2019 09:38:25 +0800 [thread overview]
Message-ID: <20190628013826.4705-1-xiaowei.bao@nxp.com> (raw)
The PCIe controller of layerscape just have 4 BARs, BAR0 and BAR1
is 32bit, BAR3 and BAR4 is 64bit, this is determined by hardware,
so set the bar_fixed_64bit with 0x14.
