Hi Alex,
Thanks for the patch Alex. This would also require support in Qemu to expose
the physical address to the VM. Are you looking at that part as well?

is_power_of_2 requires an unsigned long parameter which would
lead to truncation of 64 bit values on 32 bit architectures.
__ffs also expects an unsigned long parameter thus won't work

We maintain a list of bus types (for which iommu ops are registered). In the
iommu_domain_alloc
function we ensure that all bus types correspond to the same set of iommu

Store iommu domain information in the device structure.
Store the platform device information corresponding to the pci
controller.
Added defines for the FSL PCI controller BRR1 register.
Add window permission flags for iommu_domain_window_enable
Add a new field in the device (powerpc) archdata structure for storing iommu
