>From 8e35049a90ac8a89e843c637912181dcadb978cb Mon Sep 17 00:00:00 2001
From: Stefan Tauner <stefan.tauner@student.tuwien.ac.at>
Date: Sun, 19 Aug 2012 02:09:23 +0200
Subject: [PATCH] Refactor the -p internal:mainboard handling.

This patch gets rid of some global variables and makes lots of bits along
the code path that control the board enable execution more generic and
clearer. From now on flashrom aborts on a few more occasions that should be
safer for the user. For example it aborts if the enable function for the
specified mainboard (enable) can not be found.

Parts of the board_match_cbname refactoring were done by Carl-Daniel.
