This series adds support for RISC-V IOMMU on ACPI based platforms. RISC-V IO Mapping Table (RIMT) is a new static ACPI table [1] introduced to communicate IOMMU information to the OS. The first patch in the series is a ACPICA patch which is already available in linux-next but included in this series for completeness only.
