Thank you for the head start.
Yes, I suspected I would find the problem in panda.c. I was planning to do a diff of that file between the versions and see if anything jumped out at me.
I should be able to get it sorted this weekend. I'll let you know what I find.
Thanks again.

It's all in the Fedora package repository for uboot-tools.
"fedpkg clone uboot-tools; cd uboot-tools; fedpkg prep" will get you a
fully patched tree.

Yes, it's a problem even with vanilla upstream. I see it on my
Panda-ES too but just ran out of time to get to the bottom of the
problem with it. I did report it upstream [1] but never got a response
but I suspect there's some issue in the board/ti/panda/panda.c which
might not be setting up the board specifics
You can interrupt the boot and run the command "setenv fdtfile
omap4-panda-es.dtb" and then just run "boot" and it'll have the
correct .dtb set and it might get you further and might help you
debug.

You could test the 2015.04 rc1 in F-24 on F-22 and see if it's fixed
it, I've been traveling and not had time to look at it closer.
