From 3d07ee23c7746c6a4d3bdd8b4a736b9e906490e3 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Mon, 4 Feb 2013 13:28:01 +0000 Subject: hw/arm_sysctl: Implement SYS_CFG_DVIMODE as a no-op SYS_CFG_DVIMODE allows the guest to select whether the output DVI signal is VGA, SVGA, XGA, SGA or UXGA. Since this makes no difference to QEMU, implement writes as a no-op so Linux doesn't complain.
