From 3129f792f77e310ea246503f8b68b76fc269cfd2 Mon Sep 17 00:00:00 2001 From: Vladimir Serbinenko Date: Wed, 15 Oct 2014 21:51:47 +0200 Subject: autoport: Write autoport together with porting guide for sandy/ivybridge. This should be able to generate bootable ports for sandy/ivy, possible with minor fixes.
