Host1x's CDMA can't access the command buffers if IOMMU and Host1x firewall are enabled in the kernels config because firewall doesn't map the copied buffer into IOVA space. Fix this by skipping IOMMU initialization if firewall is enabled as firewall merges sparse cmdbufs into a single contiguous buffer and hence IOMMU isn't needed in this case.

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 Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
