The CMA driver that registers these nodes will have to be expanded to export them using this framework as needed. We do something similar to export SRAM nodes:

Unlike the system/default-cma driver which can be centralized in the tree, these extra exporters will probably live out in other subsystems and so are added in later steps.

I was under the impression that the "cma_for_each_area" loop in patch 4 would do that (add_cma_heaps). Is it not the case?
