[Qemu-arm] [RFC 0/8] VIRTIO-IOMMU device

[Eric Auger]

This series implements the virtio-iommu device. This is a proof
of concept based on the virtio-iommu specification written by
Jean-Philippe Brucker [1]. This was tested with a guest using
the virtio-iommu driver [2] and exposed with a virtio-net-pci
using dma ops.

The device gets instantiated using the "-device virtio-iommu-device"
option. It currently works with ARM virt machine only as the machine
must handle the dt binding between the virtio-mmio "iommu" node and
the PCI host bridge node. ACPI booting is not yet supported.

This should allow to start some benchmarking activities against
pure emulated IOMMU (especially ARM SMMU).

Best Regards

Eric
