To test this PRU stuff should I use Mainline or TI BSP? whats the difference?

As we speak Im cloning the TI BSP version and looks like somehow I am on 4.14 
Branch . I had bad internet last night and I lost the building during resolve 
after downloading the entire kernel of mainline . Today Im trying TI BSP 

cloning https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git into 
default location: /home/lazarman/am335x/ti-linux-kernel-dev/ignore/linux-src
