The recommendation is for IOMMU to be enabled manually on systems as needed. A recent exynos_drm change added a warning message when EXYNOS_IOMMU is disabled. It is necessary to enable it to avoid the warning messages. A few initial tests have shown that enabling EXYNOS_IOMMU might be safe on Exynos Chrome-books. Enable CONFIG_EXYNOS_IOMMU in exynos_defconfig.
