Is there a device tree porting HOWTO anywhere? If I have a board that's using explicit C initialization, and I want to convert it over to device tree, step by step what do I do? If I'm writing a new board support, what device tree bits do I need to get a shell prompt on a serial port running out of initramfs? (Physical memory, interrupt controller, timer to drive the scheduler, serial chip...) There's a bunch of device tree reference material out there, but no tutorial material at all, that I can find...
