From 00909b585861ee3dca15f3d7624aac9be0f9080f Mon Sep 17 00:00:00 2001 From: Julian Brown Date: Tue, 7 Feb 2017 18:29:59 +0000 Subject: [PATCH] hw/arm/integratorcp: Support specifying features via -cpu Since the integratorcp board creates the CPU object directly rather than via cpu_arm_init(), we have to call the CPU class parse_features() method ourselves if we want to support the user passing features via the -cpu command line argument as well as just the cpu name. Do so.
