At v2013.07-rc1, it was good. I tried 'git bisect' and got this result.
$ git bisect good 35fc84fa1ff51e15ecd3e464dac87eb105ffed30 is the first bad commit commit 35fc84fa1ff51e15ecd3e464dac87eb105ffed30 Author: Simon Glass sjg@chromium.org Date: Tue Jun 11 11:14:47 2013 -0700
Refactor the bootm command to reduce code duplicationPlease take a look.
Thanks for letting me know - also there is another thread about this.
I will post some v2 patches soon, perhaps you can try to test and report back.
