Subject[PATCH] ARM: exynos_defconfig - enable CONFIG_EXYNOS_IOMMU
Date
EXYNOS_IOMMU is disabled in exynos_defconfig since it is known to cause
boot failures on Exynos Chrome-books. 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.
