From b4a738bf93c3137b92d532e59d60edccc4e1ea96 Mon Sep 17 00:00:00 2001 From: Anthony Liguori Date: Wed, 22 Aug 2012 15:22:05 -0500 Subject: [PATCH] boards: add a 'none' machine type to all platforms This allows any QEMU binary to be executed with: $QEMU_BINARY -M none -qmp stdio Without errors from missing options that are required by various boards. This also provides a mode that we can use in the future to construct machines entirely through QMP commands.
