| 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. |
