processors.

[Thomas:
 - Remove the mention "This package is provided by Freescale as-is and
   doesn't have an upstream." from the Config.in help text, since
   according to Gary Bisson, there is a Git repository for such
   projects, and therefore some form of upstream.
 - Add missing entry to DEVELOPERS file.]
