Hi Joerg,
Please pull these ARM SMMU updates for 3.13. The bulk of the changes are
from Andreas, who has been having fun running the driver on real hardware. I
expect some additional patches from him in the future to add support for
things like device isolation once we've ironed out the wrinkles
Once the PCIe device assigned to a guest VM (via VFIO) gets detached from the
iommu domain
(when guest terminates), its PAMU table entry is disabled. So, this would
prevent the device
from being used once it's assigned back to the host.
This patch allows for creation of a default DMA window
Introduce handling of driver options. Options are set based on DT
information when probing an SMMU device. The first option introduced
is arm,smmu-isolate-devices. (It will be used in the bus notifier
block.)

In such a case we have to use secure aliases of some non-secure
registers.
This handling is switched on by DT property
arm,smmu-secure-config-access for an SMMU node.

Hi,
Here is v2 of arm-smmu changes to support SMMUs on Calxeda ECX-2000.
Note that patch 7/7 (Introduce automatic stream-id-masking) is not
required to support SMMUs on Calxeda ECX-2000. In fact the algorithm
implemented won't help to determine a suitable smr-mask for 10
StreamIDs that we have
