From e483639ad2fe0f3f9425b218bf6c37b9fbafc78f Mon Sep 17 00:00:00 2001 From: Bryan O'Donoghue Date: Thu, 29 Nov 2018 15:59:14 +0000 Subject: [PATCH] warp7: Define DTB overlay address in memory map This patch defines the expected DTB overlay address in the memory map for this platform. Its important that all points in the boot process agree on this memory map even if not all elements utilize it.
