Instead of adding explicit build rules for each and every board to the top level Makefile (which makes it grow and grow), we now provide a simple default rule and extend the "mkconfig" script to read board configurations from a plain text file (table), "boards.cfg". For simple boards it is now sufficient to add a single line of text to the "boards.cfg" file, no changes to the top level Makefile are needed any more. To make the table better readable, change the notation for unused fields from "NULL" into "-".
