Host DDR memory (contiguous 45 MB in mode-0 or 15 MB in mode-2) is reserved through DT entries for firmware usage. Send the base address from DT entries. If DT entry is available, PCI device will work with fixed_mem_region else host allocates multiple segments. IPQ8074 on HK10 board supports multiple PCI devices. IPQ8074 + QCN9074 is tested with this patch.

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.
