From 99884ad4e77a54b7e56f65f444179169bc495c35 Mon Sep 17 00:00:00 2001 From: Liviu Dudau Date: Mon, 9 Jun 2014 16:27:10 +0100 Subject: [PATCH] arm64: Juno: Carve out memory reserved for secure access. Trusted Firmware 0.4 reserves the top 16MB of RAM available in the first 4GB address space for the secure world use. Carve out that memory from the device tree to avoid triggering faults when accessing protected memory.
