>Having worked with devicetrees and hated it, I don't like this idea. I don't like the modern world of ARM and embedded where you have hardcoded firmware images for every single device. I like the x86 model, where you have a one size fits all boot disk which just loads different drivers. You don't port your OS to a new computer, you just write drivers for the new hardware parts. And your hardware describes itself to the OS.

Having worked with ARM too I have to disagree. I found device trees really flexible and easy to get going.

However, I worked with Rockchip hardware so I had pretty good documentation, lots of examples, and source code for everything(for an old linux kernel, but still). This basically ensured I could do everything I wanted.

Of course, when a vendor doesn't provide documentation and example driver source this may not be so easy.
