I tried to used mainline kernel, but board doesn't boot up. I get only
following output:

U-Boot 2013.10-rc3 (Jan 18 2015 - 12:03:56)

After this, board stuck. I also encountered this issue with another
i.MX6 based board but I didn't fix that yet. Kernel from UDOO
repository works fine.

I'm new in embedded Linux development. I still have a lot to learn,
so I would be grateful if someone points me to how to use mainline kernel.
