This is difficult, since there is no clear search criterium. Examples are

Can we please get a list of each of the BSPs which fall in to each group?
Are you able to provide a simple technical break down about each
group, eg reusable, SMP, user support, etc?
We should select the preferred model and then determine what we can do
to move all code to that model.
We lack support for a proper SPI driver framework.
