Actually I'm just in the process of answering your question. My immediate response would have been "use -t for mkconfig" but this does not (yet) work for boards.cfg versions. So I'm just in the process of testing a mkconfig extension to allow for similar handling of "BOARD_OPTION1_OPTION2" configurations which will be split into 'CONFIG_MK_{BOARD,OPTION1,OPTION2}' defines. When we have this, we can use a common config file and use #ifdefs for these CONFIG_MK defines.
