Subject: [PATCH 0/2] MT8173 IOMMU 4GB MODE SUPPORT
Date: Wed, 24 Feb 2016 07:02:30 +0800 [thread overview]
Message-ID: <1456268552-16635-1-git-send-email-yong.wu@mediatek.com> (raw)
This patch-set add MTK 4GB mode support on the Short-Descriptor.
MTK extend the bit9 of the standard pgtable descriptor as the 4GB mode.
We add a special quirk for this.
This two patches are based on Robin's Short-decriptor v3[1], MTK
IOMMU v10[2] and Robin's "Rationalise quirk handling"[3].
