A kernel is a very complex with lots of config options. It's
impossible to tell what you could be doing right or wrong

At the very least it looks like you're trying to boot a 3.4 kernel
with a 3.17.4 device tree, this won't work.

Can you boot the device with a standard Fedora kernel with the device
tree shipped with that?
