Subject: PCI: rockchip: Set address alignment for endpoint mode
From: Damien Le Moal <dlemoal@xxxxxxxxxx>
commit 7e6689b34a815bd379dfdbe9855d36f395ef056c upstream.
The address translation unit of the rockchip EP controller does not use
the lower 8 bits of a PCIe-space address to map local memory. Thus we
must set the align feature field to 256 to let the user know about this
constraint.
