The another way is to directly use dtb binary file, but bin file also 
has a gpl2 license. So this way is not acceptable.
Gedare said the scripts directory may be appropriate for rtems-tools.git 
or something. So i can provide a default one that can be used, it may be 
downloadable from somewhere e.g. in rtems-tools or from a FTP.
And this is the way to keep GPL code from RTEMS sources.
What do you think about?
