IMHO *_defconfigs are only=20 examples of board configuration, that are known to build and work. The=20 rest is up to the user / packager. > Perhaps similar remarks would apply to the other device that you > maintain?

Feel free to submit patches with reasoning to the powerpc ML and=20 respective maintainer as per MAINTAINERS file.
