i am not sure if this is a good idea. there are thousands of events
being broadcast, specially during boot and we really want to avoid
respawning the script helper for each one of them. i was under the
impression that we had an include directive that allowed us to include
board/target specific json files. however i am failing to find the code
that does this so the feature might not actually be implemented yet.
i'll need to have a closer look at this the next days.
