In order to create a CMA dma-buf heap instance for each CMA heap region in the system, we need to collect all of them during boot. They are created from two main sources: the reserved-memory regions in the device tree, and the default CMA region created from the configuration or command line parameters, if no default region is provided in the device tree. Let's collect all the device-tree defined CMA regions flagged as reusable. Reviewed-by: T.J.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
