From 704033cee2e5b3c1c6eaf5bb398e465a9c3667b5 Mon Sep 17 00:00:00 2001 From: Laura Abbott Date: Tue, 15 Jul 2014 10:03:35 -0700 Subject: of: Add memory limiting function for flattened devicetrees MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Buggy bootloaders may pass bogus memory entries in the devicetree. Add of_fdt_limit_memory to add an upper bound on the number of entries that can be present in the devicetree.
