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.
In principle I like the idea of having configuration retrieved from the device tree blob, but the idea of reflashing the blob in the context of u-boot scares me. In particular, if u-boot depends too much on the presence of the blob, then it becomes a method of bricking a board if users are able/expected to reflash the blob.
