This copy of flashrom is old and unmaintained. Delete it to avoid
confusion, after we had a grace period to get people to move over to the
new repository.
History stays available for the archaeologists and for ancient
checkouts (potentially with local changes). Use "svn diff" to get local
changes, and apply it to a newer tree (if you manage to apply it, that
is).
The new repository is available at:
svn://coreboot.org/flashrom/trunk
