3.13.11.4 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Petazzoni <thomas.petazzoni@xxxxxxxxxxxxxxxxxx>
commit b566e782be32145664d96ada3e389f17d32742e5 upstream.
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.
Fixes: fddddb52a6c4 ('bus: introduce an Marvell EBU MBus driver')
