The PCIE_AXI_WINDOW0 register defines the inbound window size for requests coming from PCI endpoints. Requests outside of this window will be treated as unsupported requests. Enlarge this window size from 2^31 to 2^33 to support a 8GB address space (which gives endpoints DMA access to full 4GB DRAM address range - physical DRAM starts at 0x40000000).

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.
