From 4c8ac10737ae38256d59406801591d9dca2bd69b Mon Sep 17 00:00:00 2001 From: "Edgar E. Iglesias" Date: Mon, 16 Apr 2018 22:23:05 +0200 Subject: [PATCH] target-microblaze: Fallback to our latest CPU version 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.
