From b566e782be32145664d96ada3e389f17d32742e5 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Fri, 18 Apr 2014 14:19:52 +0200 Subject: [PATCH] bus: mvebu-mbus: allow several windows with the same target/attribute Having multiple windows with the same target and attribute is actually legal, and can be useful for PCIe windows, when PCIe BARs have a size that isn't a power of two, and we therefore need to create several MBus windows to cover the PCIe BAR for a given PCIe interface.
