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.
v4: Rebased on top of Cannonlake patches.
