From 891f3bc37fb9dd81a27d19edc091be2603c9c176 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 2 Mar 2018 10:45:36 +0000 Subject: [PATCH] hw/arm/armv7m: Honour CPU's address space for image loads MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Instead of loading guest images to the system address space, use the CPU's address space. This is important if we're trying to load the file to memory or via an alias memory region that is provided by an SoC object and thus not mapped into the system address space.
