ACPI IORT is an ACPI addendum to describe the connection topology of devices with IOMMUs and interrupt controllers on ARM64 ACPI systems. Currently the ACPI IORT Kbuild symbol is selected whenever the Kbuild symbol ARM_GIC_V3_ITS is enabled, which in turn is selected by ARM64 Kbuild defaults. This makes the logic behind ACPI_IORT selection a bit twisted and not easy to follow. On ARM64 systems enabling ACPI the kbuild symbol ACPI_IORT should always be selected in that it is a kernel layer provided to the ARM64 arch code to parse and enable ACPI firmware bindings. Make the ACPI_IORT selection explicit in ARM64 Kbuild and remove the selection from ARM_GIC_V3_ITS entry, making the ACPI_IORT selection logic clearer to follow.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
