X-Received-From: 2001:8b0:1d0::2 Subject: [Qemu-devel] [PATCH 03/19] hw/arm/armv7m: Honour CPU's address space for image loads X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: patches@linaro.org Errors-To: qemu-devel-bounces+importer=patchew.org@nongnu.org Sender: "Qemu-devel" X-ZohoMail: RSF_0 Z_629925259 SPT_0 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.
