From 804bf578437c1ff33930aa73c8e536532608691a Mon Sep 17 00:00:00 2001 From: Liviu Dudau Date: Mon, 9 Jun 2014 16:27:10 +0100 Subject: 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.
