RISC-V IO Mapping Table (RIMT) provides the information about the IOMMU to the OS in ACPI. Add support for ACPI in RISC-V IOMMU drivers by using RIMT data. The changes at high level are, a) Register the IOMMU with RIMT data structures. b) Enable probing of platform IOMMU in ACPI way using the ACPIID defined for the RISC-V IOMMU in the BRS spec [1]. Configure the MSI domain if the platform IOMMU uses MSIs.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
