[U-Boot-Users] using a flat device tree to drive u-boot config

One topic that come up during OLS in discussions and u-boot BOF was the idea of driving u-boot configuration from a device tree instead of from "config.h". I was wondering if anyone has actually looked at doing this.

One question I have is how does (or should) u-boot identify where to find the device tree. I think the idea would be that this "area" could be easily reflashed with a new blob to get a new configuration.
