Ohad Ben-Cohen cfb470b336 ARM: 7130/1: dev_archdata: add private iommu extension ... Add a private iommu pointer to the ARM-specific arch data in the device struct, which will be used to attach iommu-specific data to devices which require iommu support. Different iommu implementations (on different platforms) will attach different types of data to this pointer, so 'void *' is currently used (the downside is reduced typesafety). Note: ia64, x86 and sparc have this exact iommu extension as well, and if others are likely to adopt it too, we might want to consider adding this to the device struct itself directly.
