This will be largely targeted towards Rafal who supports these kinds of 
devices with an upstream kernel. My understanding is that this is OK 
because we will always ship a DTB matching the Linux kernel, and I 
believe this is true for both the way that William and his group support 
these devices, as well as how OpenWrt, buildroot or other build systems 
envision to support these devices.

Rafal, does that sound about right?
