[PATCH AUTOSEL 4.19 066/101] PCI: mobiveil: Fix PCI base address in MEM/IO outbound windows

From: Sasha Levin
Date: Fri Jul 19 2019 - 00:24:14 EST


From: Hou Zhiqiang <Zhiqiang.Hou@xxxxxxx>

[ Upstream commit f99536e9d2f55996038158a6559d4254a7cc1693 ]

The outbound memory windows PCI base addresses should be taken
from the 'ranges' property of DT node to setup MEM/IO outbound
windows decoding correctly instead of being hardcoded to zero.

Update the code to retrieve the PCI base address for each range
and use it to program the outbound windows address decoders
