commit 2cd6bf3653a2b983c90bf3af42d199c499db4165
Author: Ian Campbell <ian.campbell@xxxxxxxxxx>
Date:   Wed May 14 15:12:01 2014 +0100

    tools: arm: remove code to check for a DTB appended to the kernel
    The code to check for an appended DTB was confusing and unnecessary. Since 
    know the size of the kernel binary passed to us we should just load the 
    thing into guest RAM (subject to the limits checks). Removing this code 
    a whole raft of overflow and alignment issues.
    We also need to validate the limits of the segment where we intend to load 
    kernel to avoid overflow issues.
    For ARM32 we control the load address, but we need to validate the size. The
    entry point is only relevant within the guest so we don't need to worry 
    For ARM64 we need to validate both the load address (which is the same as 
    entry point) and the size.
    This is XSA-95.

    xen/passthrough: Introduce IOMMU ARM architecture
    This patch contains the architecture to use IOMMUs on ARM. There is no
    IOMMU drivers on this patch.
    In this implementation, IOMMU page table will be shared with the P2M.
    The code will run through the device tree and will initialize every IOMMU.
    It's possible to have multiple IOMMUs on the same platform, but they must
    be handled with the same driver. For now, there is no support for using
    multiple iommu drivers at runtime.
    Each new IOMMU drivers should contain:
    static const char * const myiommu_dt_compat[] __initconst =
        /* list of device compatible with the drivers. Will be matched with
         * the "compatible" property on the device tree
            .compatible = myiommu_compatible,
            .init = myiommu_init,

    x86 specific fields.

    iommu: split generic code
    The generic IOMMU framework code (xen/drivers/passthrough/iommu.c) contains
    functions specific to x86 and PCI.
    Split the framework in 3 distincts files:
        - iommu.c: contains generic functions shared between x86 and ARM
                   (when it will be supported)
        - pci.c: contains specific functions for PCI passthrough
        - x86/iommu.c: contains specific functions for x86
    io.c contains x86 HVM specific code. Only compile for x86.
    This patch is mostly code movement in new files.
