This uclass is intended to manage IOMMUs on systems where the IOMMUs are not in bypass mode by default. In that case U-Boot cannot ignore the IOMMUs if it wants to use devices that need to do DMA and sit behind such an IOMMU. This initial IOMMU uclass implementation does not implement and device ops and is intended for IOMMUs that have a bypass mode that does not require address translation. Support for IOMMUs that do require address translation is planned and device ops will be defined when support for such IOMMUs will be added. Signed-off-by:

Some SoCs use a different address map for CPU physical addresses and
peripheral DMA master accesses. If yours does, select this option in
your platform's Kconfig, and implement the appropriate mapping
functions in your platform's support code.
