Oh well, if you can and can convince the ARM kernel folks to do the necessary changes ... :-) One thing tho, you will only benefit from the whole infrastructure we have created accross platforms in linux if the device-tree is "sucked" into linux at boot. IE. Linux will not do constant accesses to OF for the DT. Even sparc converted to that now. That means that if your device-tree has a dynamic nature, we'll need to come up with a way to inform the kernel of changes in it so it can update it's copy accordingly. We also don't have much mechanisms within Linux to notify users that things have changed either. It only really happens on IBM pseries for hotplug, which uses a private notifier.
