Stephen had pretty strong opinions on the naming, mostly because "pxe
boot" uses the same naming scheme. So we should either change it there
as well to stay consistent or just make the implicit ruling always work :).
I guess the best case would be to fix up the path names of boards so
that $vendor is always $soc_vendor. Do you have an example where that
wouldn't work?
