Looks pretty good so far!
For the benefit of everyone who missed the excitement on IRC, there is one major caveat to this patch: Those using a git repository probably have stale SVN metadata, which means the upstream Flashrom SVN information in the version string will be incorrect.
For example, if I clone the Chromium OS flashrom branch (git clone
http://src.chromium.org/git/flashrom.git) and run "git svn info", I'll get a message saying "Unable to determine upstream SVN information from working tree history." After adding the upstream SVN repo as a remote repository and doing "git svn fetch", I'll get something like this:
dhendrix@thegates:flashrom$ git svn info
Path: .
Repository UUID: 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
Revision: 1011
Node Kind: directory
Schedule: normal
Last Changed Author: uwe
Last Changed Rev: 1011
Last Changed Date: 2010-05-24 10:39:14 -0700 (Mon, 24 May 2010)
In this example, r1011 is incorrect.
Using Carl-Daniel's script in the same repo, I get:
dhendrix@thegates:flashrom$ sh /tmp/cdh.sh
Repository UUID: 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
Revision: 1145
Last Changed Author: hailfinger
which is (currently) correct.
Now to figure out how best to integrate this... Can we put the script in util/ and have the Makefile invoke it when it detects we're using a git repo?

flashrom relies on svn to export tarballs and only prints the last svn
revision in the version message even if flashrom is in a git tree.
Print extended version information (version, svn revision, git hash,
repository URL).
Allow exporting from git trees.
This should make git users first-class citizens like svn users.
Side note: If anyone has an idea how to make the export target more
beautiful (80 column limit etc.), please tell me.
