Hi,
I tested this patchset on my board using an imx23. It seems OK.

I didn't manage to get your git tree:
$ git remote add -f jbe http://git.pengutronix.de/git/jbe/for_barebox_next
Updating jbe
fatal: http://git.pengutronix.de/git/jbe/for_barebox_next/info/refs
not found: did you run git update-server-info on the server?
error: Could not fetch jbe
Indeed http://git.pengutronix.de/git/jbe/for_barebox_next/info/refs
does not exist.
Maybe I did something wrong or maybe be you have to run git
update-server-info on the server ;)

Sorry, I'm not a git expert. But this will show the content:

Don't know, what's wrong.

The problem was that I used http protocol instead of git protocol.
this command finally worked perfectly:
$git remote add -f jbe git://git.pengutronix.de/git/jbe/for_barebox_next
Thanks to Eric Bénard for his advice.

You need to do
cd /path/to/your/for_barebox_next-repo
git update-server-info
(to fix this for now and )
mv hooks/post-update.sample hooks/post-update
(to assert it stays fixed when you push the next time.)
But in general git:// is preferable because it only transfers the needed
objects (in contrast to the complete history when the repository is
perfectly packed even you only miss a single object).
Best regards
Uwe

try using git protocol instead of http, this works on other tree on the
pengutronix git server :
git://git.pengutronix.de/git/jbe/for_barebox_next
