Emebdded Device Tree Support in U-Boot
======================================
This directory contains a Makefile for building the device tree blob and
embedding it in your U-Boot image. This is useful since it allows U-Boot to
configure itself according to what it finds there. If you have a number of
similar boards with different peripherals, you can describe the features of
each board in the device tree file, and have a single generic source base.
Put your device tree file in board/<vendor>/dts/<soc>_<board>.dts. It will be
picked up and built into the image.
To do
=====
- Provide a way for U-Boot to find a device tree somewhere in memory on startup,
similar to how the environment works.
