First, let me say I don't find the configurator that we are talking about all 
the helpful to my work, but I think I might have a solution that will reduce 
the maintainability. So what I was thinking about was using the maintainers 
file along with a configurator script in the tools directory. The 
configurator would be all the smarts. It would read the MAINTAINERS file,  
which has the bits in a well-defined structure, and generate the views with 
some type of filtering. So you could say "Show me all boards supporting CPU 
xyz" or "Show me all boards supported by CPU xyz". The obvioous final step of 
the configurator is "make <configuration>"

Here are the pros and cons I see to this:

* The only new files are specificaly for the configurator and only need be 
modified to fix the configurator.
* Only the people interested in the system need to know about it.
* Automatically updated with each supported board.
* Minimal added work for Wolfgang.
* It can be extracted from the tree and maintained on the side until Wolfgang 
has the time to review and appove it.
* No one other then the interested parties has to do anything other than add 
their board to the MAINTAINERS list to work in u-boot.
* It does not preclude the make <configuration> well known system.
* Many others I am sure :)

* More files in the u-boot tree.
* The configurator itself becomes somewhat complex.
* Many others I am sure :)

Jon, Wolfgang what are your thoughts on a system like this?
