These config-expanions files contain source commands for different 
expansions like HDMI, LCD, WiFi, ... and are written from Yocto. We 
don't want to bring these mainline, but without this line we have to 
overwrite each boot script file from Yocto.

Maybe this could be a good feature since we're not the only one with 
expansion configurations.
