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.
This sounds like an interesting idea, having a central repo for all hardware information. A big problem I see is that while device-tree syntax may make sense to Linux kernel propellerheads, to the average Joe it's mind-numbing. Config files are ugly, but at least IMHO are easy to figure out. User-friendly editing tools would be a necessity. Maybe something already exists?
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.
This should be fun considering the plethora of architectures that U-boot supports.
