From 385eb90c8cd31bfb770a950dd9252a30ccd6955d Mon Sep 17 00:00:00 2001
From: Leah Rowe <leah@libreboot.org>

Subject: update/*/*: unified scanning of revisions/sources

update/blobs/download and update/project/repo both use
the same logic, for setting variables with awk and a
specially formatted configuration file.

unify this logic under include/option.sh, and use that.
