Please explain the exact requirements that lead you to defining

Some devices may have access only to some banks of memory.  Some devices
may use different banks of memory for different purposes.

Maybe.  I'm just answering your question. :)

Ah yes, I forgot that separate regions for different purposes could
decrease fragmentation.

I would suggest going forward without having multiple regions:

Is having support for multiple regions a bad thing?  Frankly,
removing this support will change code from reading context passed
as argument to code reading context from global variable.  Nothing
is gained; functionality is lost.

* Remove the registration of specific addresses from the initial patch
  set (but keep the patch).
* Add a heuristic plus command-line override to automatically come up
  with a reasonable location+size for *one* CMA area in the system.

I'm not arguing those.
