I'd love to see somebody pick up the bits of information they gather on the device tree and write a doc on that in Documentation/ (which gets rendered to doc.coreboot.org). Andy, willing to take that on? :-)
I’m happy to give it a try but it will have to wait until I’ve finished doing battle with this machine and got it all working!

GPIO pin definitions and an Embedded Controller are the current headache!  I seem to keep finding new ways to make it stop at POST_FSP_SILICON_INIT!
