I've never found vendor provided OE BSP layers to be easy to use or useful beyond initial proof-of-concept type work. In general, hardware vendor provided software has sucked greatly in my experience. Taking the vendor provided thing and then removing a lot of the junk, or taking the upstream software project and then selectively cherry-picking some key changes which the vendor has made works pretty well. But this isn't a fast process and requires quite a bit of education about how/why the vendor has done things a certain way and how the upstream open source code in question works. But long term it's been a much better solution for the projects I've worked on when I've been able to do this.
