The current MBUS DRAM window calculation fails for 4GB windows because it overflows. This is fixed in the first patch by using u64 instead of u32 to store the size. The second excplicitly checks that we don't try to configure a too large memory window in the pci driver. As they don't depend on each other, they could also go in separatly.

Since these can be applied separately, I'll let somebody else take care of the drivers/bus/mvebu-mbus.c part. I'll look for an ack from Thomas or Jason before applying the second patch, which touches drivers/pci/host/pci-mvebu.c.
