From cf63dad014bae080445bccbf9cecbe05f2cbed45 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Fri, 21 Dec 2018 17:30:46 +0100 Subject: [PATCH] arm64: dts: marvell: armada-ap806: reserve PSCI area The memory area [0x4000000-0x4200000[ is occupied by the PSCI firmware. Any attempt to access it from U-Boot leads to an immediate crash. So let's make the same memory reservation as the vendor device tree.
