Embedded Linux Conference Europe

As we all know Linus is a colorful character, but his taste in software design is impeccable. So it was hardly a big surprise when the famous edict about having all new ARM boards to use Device Tree, instead of a board file, was made. That single change forced a momentous shift in Linux based embedded software development, since a long list of cherished idioms (and a lot of questionable practices) have had to change. Device Tree due to it's purely data driver model, and focus on reusability, is quite tricky to come at terms at first, which is something we discovered during our porting efforts of the Beaglebone board support to DT. Join me in discussing they why, the how, and learn the hard lessons we at Beagleboard have learned moving to this new paradigm.
