The SoC DMA resources for UDMA, BCDMA and PKTDMA can be described via a combination of up to two resource ranges. The first resource range handles the default partitioning wherein all resources belonging to that range are allocated to a single entity and form a continuous range. For use-cases where the resources are shared across multiple entities and require to be described via discontinuous ranges, a second resource range is required. Currently, udma_setup_resources() supports handling resources that belong to the second range. Extend bcdma_setup_resources() and pktdma_setup_resources() to support the same.

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.
