The top level Makefile is growing and growing. Once, when we supported only a few tens of boards, it was possible to implement board configuration logic in the Makefile, but it quickly turned out that this doesn't scale. Also, it is not really needed (at least not any more) - we now have mechanisnms in place, that allow for more efficient code.
The following patch series is an attempt to start some cleanup and reduce the size of the top level Makefile. The solution is neither perfect nor complete - there are quite a lot of boards that resist such a cleanup and need more thorough rework. But it's an initial step, showing what could and should be done, which boards have problems, and why this is the case. Eventually this paves the ground for a more friendly way to add new board configurations.
The idea is to have all "board descriptions" in a single data base in form of a plain text file - no need to add anything to the top level Makefile, and eventually also tools like the "MAKEALL" script can be replaced / simplified because they can fetch all needed board information from that data base.
