The ARM PL081 DMA controller can be found in the BCM6846 memory map, and it turns out to work. The block may be used as DMA engine for some of the peripherals (maybe the EMMC controller found in the same group of peripherals?) but it can always be used as a memcpy engine, which is a generic "blitter". I tested it with the dmatest module, and it copies lots of data very fast and fires hundreds of thousands of interrupts so it works just fine. Add it to the BCM6846 DTSI file.

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.
