The config space is divided in half for type 0 and type 1 accesses, but this is pointless as there's only one iATU window which is reconfigured on each access. The only platform doing something custom is TI Keystone (surprise!). It does its own mapping of the config space to avoid spliting the config space and never actually uses va_cfg1_base as it has its own config space accessors. With the splitting removed, Keystone can use the default mapping of config space.

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.
