From ec2eaa73b3d21776f46797a2eef983d7be09a964 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Sun, 25 Aug 2013 16:47:48 -0500 Subject: [PATCH] arm64: set initrd_start/initrd_end for fdt scan In order to unify the initrd scanning for DT across architectures, make arm64 use initrd_start and initrd_end instead of the physical addresses.
