From a74029f6cbce43074793dc30534fb6b3aeab7584 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Sat, 28 Jun 2014 09:45:27 -0700 Subject: target-ppc: Change default cpu for ppc64le-linux-user The default, 970fx, doesn't support MSR_LE. So even though we set LE in ppc_cpu_reset, it gets cleared again in hreg_store_msr. Error out if a user-selected cpu model doesn't support LE.
