From 884ab569aec3a0847702dff0dad133bfb67e234c Mon Sep 17 00:00:00 2001 From: Josh Cartwright Date: Thu, 13 Mar 2014 16:36:36 -0500 Subject: [PATCH 054/182] of: only scan for reserved mem when fdt present When the reserved memory patches hit -next, several legacy (non-DT) boot failures were detected and bisected down to that commit. There needs to be some sanity checking whether a DT is even present before parsing the reserved ranges.
