From 67bfa0ee6691f62d5e2d9602d032a19716fe7b34 Mon Sep 17 00:00:00 2001 From: Alistair Popple Date: Wed, 29 Jan 2014 15:20:12 +1100 Subject: powerpc/iommu: Fix initialisation of DART iommu table Commit d084775738b746648d4102337163a04534a02982 switched the generic powerpc iommu backend code to use the it_page_shift field to determine page size. Commit 3a553170d35d69bea3877bffa508489dfa6f133d should have initiliased this field for all platforms, however the DART iommu table code was not updated. This commit initialises the it_page_shift field to 4K for the DART iommu.
