X-Received-From: 2a00:1450:400c:c09::243 Subject: [Qemu-devel] [PULL v1 04/38] target-microblaze: Fallback to our latest CPU version 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: edgar.iglesias@xilinx.com, peter.maydell@linaro.org Errors-To: qemu-devel-bounces+patchwork-qemu-devel=patchwork.kernel.org@nongnu.org Sender: "Qemu-devel" X-Virus-Scanned: ClamAV using ClamSMTP From: "Edgar E. Iglesias" Today, when running QEMU in linux-user or with boards that don't select a specific CPU version, we treat it as an invalid version and log a message. Instead, if no specific version was selected, fallback to our latest CPU version. Reviewed-by: Alistair Francis Signed-off-by: Edgar E.
