I assume the tmcu* branch is private as I don't see it in the u-boot repo.

Using -q suppresses potentially useful information. I wouldn't use it if you're not sure about what you're doing.
I would do something like this:
... (same stuff as above before with svn setup...) git clone $ORG_REPO $GIT_REPO cd $GIT_REPO git-svn init "$REPO"/trunk git-svn fetch
# sync the SVN repo with initial-uboot # this will just commit a snapshot, without history, which I assume # is what you want. git-branch initial-uboot f5e0d03970409feb3c77ab0107d5dece6b7d45c9 git-svn commit initial-uboot git checkout -b svn-branch remotes/git-svn git-pull . tmcu2
# this should work assuming the path from initial-uboot..tmcu2 is linear # use gitk initial-uboot..tmcu2 to check git-svn dcommit
Also, git-svn is really designed for individual developers who prefer to use git, but need to interact with project that already uses SVN. u-boot already uses git, so I don't see why you'd need git-svn :)
