Yeah, the only thing is that BSPs were meant to have a very minimal set of 
layer dependencies, as far as I remember our early discussions on this topic. 
So I always kept meta-ti depending only on openembedded-core and nothing else. 
To the extent that I had to remove stuff that is related to BSP, but depends 
on meta-openembedded and move it to meta-arago instead...

The alternative here would be a conditional dependency - i.e. if a layer is 
present, enable corresponding recipes, otherwise those won't be buildable and 
should be skipped...
