From 6be741114d95dcb9b8d783c114999b0e8b8b802d Mon Sep 17 00:00:00 2001
From: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net>

Subject: Allow to compile out serprog completely

If CONFIG_SERPROG is not set, no stubs and no data of serprog will
remain.

Side benefit: This kills a few dozen lines of code.

r678, r679 and r680 made this possible. Once "Only list available
programers in usage()" is committed, even the usage message will be
adjusted automatically.

Corresponding to flashrom svn r681.
