+Subject: [PATCH 1/1] me_cleaner: don't modify if -k is used
+
+don't remove *anything*. in libreboot, we only
+ever use -k when we werely want to extract the
+ME, but otherwise not modify it. this is because
+we rely on bruteforce, detecting when me.bin is
+found based on mecleaner validation.
+
+this way, we can much more reliable get the ME
+images.
