[PATCH v3 00/13] IOMMU support for ARM

[Julien Grall <julien.grall@linaro.org>]

Hello,

This is the third version of the patch series to add support for IOMMU on
ARM. It also add ARM SMMU driver which is used for instance on Midway.

The IOMMU architecture for ARM is relying on the page table is shared between
the processor and each IOMMU.

The patch series is divided following:
    - #1: fixing grant-table with IOMMU. Will be necessary for ARM later
    - #2: Remove domain_id in hvm_iommu
    - #3-#4: Adding new device tree functions
    - #5-#7: Prepare IOMMU code to add support for ARM
    - #8: Adding basic device tree assignment support
    - #9-#12: Add IOMMU architecture for ARM
    - #13: Add SMMU drivers

For now the 1:1 workaround is not removed because a same platform can have
DMA-capable device which are under an IOMMU and some not.

This series has also dependency on:
    - early printk series :
    http://lists.xen.org/archives/html/xen-devel/2014-01/msg00288.html
    - interrupt series:
    http://lists.xen.org/archives/html/xen-devel/2014-01/msg02139.html
    - few bug fixes on the previous series

A working tree can be found here:
    git://xenbits.xen.org/people/julieng/xen-unstable.git branch smmu-v3

Any comments, questions are welcomed.

Sincerely yours,
