For BSP I plan to upstream eventually.

The basic idea was to divide the project in three different patches since USB and WiFi comes from a third party and is not released under GPL (well, different story...) Keeping them in three different branches would make patch creation easier especially if fixes are checked in into the USB/WiFi branch.

At least the BSP could work on its own but for WiFi and USB you are right - it's hard to test them seperately. I just thought that there is a convenient way for handling such kind of project.

Thanks, Christian.
