[PATCH 0/2] MT8173 IOMMU 4GB MODE SUPPORT

[Yong Wu]

  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].
