Previously the target routing specifics of switch decoders and platform CXL window resource tracking of root decoders were factored out of 'struct cxl_decoder'. While switch decoders translate from SPA to downstream ports, endpoint decoders translate from SPA to DPA. This patch, 3 of 3, adds a 'struct cxl_endpoint_decoder' that tracks an endpoint-specific Device Physical Address (DPA) resource. For now this just defines ->dpa_res, a follow-on patch will handle requesting DPA resource ranges from a device-DPA resource tree.

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.
