Opps, stuck in draft's...

Today, they are the kernel directory. There is an external project
tracking just the *.dts files:

http://xenbits.xen.org/gitweb/?p=people/ianc/device-tree-rebasing.git;a=summary

I'm going to fork that repo, and add our *.dts changes, then it'll be
really easy to generate a new *.dtb on the target with
customization's...

That would be a neat option. In the back of my mind i was also
thinking some kinda html5 gui -> dts -> dtb setup.

Right now, in v3.14-ti we don't have hdmi audio, it was just posted
for v3.17-rc1, so let the backporting begin:

I want to separate the two.. There will be an option to enable hdmi
audio, or use a cape audio instead.
