The heaps could be added as module, so some functions should be exported to register dma-heaps. And dma-heap of module can use cma area to allocate and free. However the function related cma is not exported now. Let's export them for next patches.

NAK. I really don't think any module has business gaining that kind of low-level access to the various symbols. I think in general your heap can just be built-in and we should be fine.
