From 9816833d3b8ec9adfb63b6a53f1b56f5304f4c40 Mon Sep 17 00:00:00 2001 From: Gonglei Date: Wed, 3 Dec 2014 16:49:46 +0000 Subject: bootdevice: move code about bootorder from vl.c to bootdevice.c First, we can downsize vl.c, make it simpler by little and little. Second, I can maintain those code and make some improvement.
