That's an interesting request.  There isn't really a way to separate
them this way since the configuration control script is used to divide
the LHA7A400 implementation of the ARM920 from the Samsung
implementation.

I've rewritten the generation script using text tools.  It is
attached.  It uses the preprocessor to generate the list of #defines,
so I think that it better matches your expectations.
