Pull Exynos platform DT fix from Grant Likely: "Device tree Exynos bug fix for v3.16-rc7 This bug fix has been brewing for a while. I hate sending it to you so late, but I only got confirmation that it solves the problem this past weekend. The diff looks big for a bug fix, but the majority of it is only executed in the Exynos quirk case. Unfortunately it required splitting early_init_dt_scan() in two and adding quirk handling in the middle of it on ARM. Exynos has buggy firmware that puts bad data into the memory node. Commit 1c2f87c22566 ("ARM: Get rid of meminfo") exposed the bug by dropping the artificial upper bound on the number of memory banks that can be added. Exynos fails to boot after that commit. This branch fixes it by splitting the early DT parse function and inserting a fixup hook. Exynos uses the hook to correct the DT before parsing memory regions" * tag 'devicetree-for-linus' of git://git.secretlab.ca/git/linux: arm: Add devicetree fixup machine function of: Add memory limiting function for flattened devicetrees of: Split early_init_dt_scan into two parts
