Help text

Support for implementations of the RISC-V IOMMU architecture that complements the RISC-V MMU capabilities, providing similar address translation and protection functions for accesses from I/O devices.

Say Y here if your SoC includes an IOMMU device implementing the RISC-V IOMMU architecture.
