Hi Albert,
This tag NIOS2-5_0_0 keeps lingering in ARM repositories and should not be there. I regularly have to remove it from u-boot-arm because I keep catching it occasionally when recreating my u-boot-arm local copy and then fetching another ARM repo such as u-boot-atmel, u-boot-marvell, u-boot-pxa, u-boot-samsung, and u-boot-ti, which all contain this tag.
Just for your information - you can add a "tagopt = --no-tags" option to remote repositories in your .git/config like this:
[remote "arago-omapl1"] url = git://arago-project.org/git/projects/linux-omapl1.git fetch = +refs/heads/*:refs/remotes/arago-omapl1/* tagopt = --no-tags
This way, you'll never implicitely pull tags from that repository. It turned out to be helpful, so I wanted to share the tip.
Cheers Detlev
