The PLDA root complex on Juno relies on an address-based lookup table to generate AXI attributes for inbound PCI transactions, and as such will not pass any transaction not matching any programmed address range. The standard firmware configuration programs 3 entries covering the GICv2m MSI doorbell and the 2 DRAM regions, so add a "dma-ranges" property to describe those usable inbound windows.

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.
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.
