From e1d3c0fd701df831169b116cd5c5d6203ac07f70 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Fri, 14 Nov 2014 17:18:23 +0000 Subject: iommu: add ARM LPAE page table allocator A number of IOMMUs found in ARM SoCs can walk architecture-compatible page tables. This patch adds a generic allocator for Stage-1 and Stage-2 v7/v8 long-descriptor page tables. 4k, 16k and 64k pages are supported, with up to 4-levels of walk to cover a 48-bit address space.
