    xen/arm: Introduce a generic way to describe device · 6c5d3075
    Julien Grall authored
    Currently, Xen is supporting PCI and Platform device (based on Device Tree).
    While Xen only supports Platform device on ARM, Xen will gain support of
    PCI soon.
    Some drivers, such as IOMMU drivers, may handle PCI and platform device in
    the same way. Only few lines of code differs.
    Rather than requesting to provide 2 set of functions (one for PCI and
    one for platform device), introduce a generic structure "device" which
    is embedded in each specialized device.
    As x86 only supports PCI, introduce a new type device_t which will be an
    alias to pci_dev for this architecture. It will avoid to add a new field
    for this place.
