Subject:    [PATCH 1/2] acpi/iort: permit SMMU model values of 4 and 5
From:       Ard Biesheuvel <ard.biesheuvel () linaro ! org>
Date:       2019-02-20 13:59:03
Message-ID: 20190220135904.10285-1-ard.biesheuvel () linaro ! org
[Download RAW message or body]

The IORT spec was updated at some point to add support for some
additional SMMU v1/v2 implementations, i.e., the ARM MMU-401 and
the Cavium ThunderX SMMU. So permit these in the validation test.
