He'd be a great person to sponsor to get it finished/updated and checked in, then. (Or his company, code sourcry, would.) Me, I just want to use the result. By the way, device trees were a topic at this year's kernel summit, and LWN did an excellent write-up, as usual: http://lwn.net/Articles/357487/ (If it does get done, somebody needs to write a HOWTO...)
