I see those as orthogonal problems. The code can have support for
multiple contexts but by default use a single global context exported
as cma_global variable (or some such).
And I'm not arguing against having “contiguous allocation parameters
tuned automatically to just work on most boards”. I just don't see
the reason to delete functionality that is already there, does not
add much code and can be useful.
