>Subject: [PATCH 1/5] drm/i915/cfl: Introduce Coffee Lake platform definition.
>
>Coffee Lake is a Intel® Processor containing Intel® HD Graphics following
>Kabylake.
>
>It is Gen9 graphics based platform on top of CNP PCH.
>
>Let's start by adding the platform definition based on previous platforms but yet
>as preliminary_hw_support.
>
>On following patches we will start adding PCI IDs and the platform specific
>changes.
>
>v2: Also add BS2 ring that is present on GT3. As on KBL, according
> spec: "GT3 also has additional media blocks with second instance
> of VEBox and VDBox each", i.e. BSD2 ring in our case. Noticed
> when reviewing PCI ID patches.
>
>v3: CFL_PLATFORM instead for CFL_FEATURES because it contains
> Platform information and no new features when compared to
> BDW_FEATURES definition.
