[Qemu-devel] [PULL 05/21] arm: virt: Move machine class init code to the


From: Peter Maydell
Subject: [Qemu-devel] [PULL 05/21] arm: virt: Move machine class init code to the abstract machine type
Date: Wed, 16 Mar 2016 17:18:19 +0000

From: Wei Huang <address@hidden>

This patch moves the common class initialization code from
"virt-2.6" to the new abstract class. An empty property is added to
"virt-2.6" machine. In the meanwhile, related funtions are renamed
to "virt_2_6_*" for consistency.
