The HiSilicon non-ECAM PCIe has been broken since March 2016 commit
7e57fd1444 ("PCI: designware: Move Root Complex setup code to
dw_pcie_setup_rc()"). The reason is this commit moved the iATU setup code
from dw_pcie_host_init() to dw_pcie_setup_rc(), but the hisi driver never
calls dw_pcie_setup_rc(). The result is the PCI memory space is never
configured and the driver can't work. It's also clear it has an iATU as
the config space accesses use it.
There's also no dts file using either "hisilicon,hip05-pcie" or
"hisilicon,hip06-pcie".

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.
