DMC provides additional graphics low-power idle states. It provides
capability to save and restore display registers across these low-power
states independently from the OS/Kernel

This is the first release of DMC for Cannonlake.

This major version will be just upgraded on code when it is required
software changes for API/ABI compatibility.

For some reason these 2 files got corrupted
when propagating the release to this repository.

i915 firmware got first release at:
https://01.org/linuxgraphics/downloads/firmware


then propagated to linux-firmware.git.

The version on 01.org are the right ones.

This issue has been identified by Jason. He
noticed that GuC image from linux-firmware.git
wasn't getting loaded on his Kabylake, while
the version on 01.org was working propertly.

In a further review I identified that also GuC
image for Broxton faced a similar issue. All other
files on i915 are the proper one matching with
the ones released on 01.org.

1.26 is the stable and recommended firmware for Skylake.
However one conflict in i915 accidentally restored 1.23
making that the default in some kernel out there.

So, let's restore this 1.23 here.

i915 now loads the specific major/minor version of the firmware
instead of loading the symbolic links.

So this patch also removes symbolic links from the firmware
components that never had the firmware loaded directly and
let the symbolic links only for the cases where some versions
of i915 might load the symbolic link while new versions loads
the file directly.

I considered making copies but this would
increase this repository size in ~ 25%.

The symbolic links now on shall never be updated.

This is the first version of the FW for KBL.

Although we are stepping back from symbolic links,
when kbl_dmc_ver1_01 was introduced there was the link
so let's keep it around for a while.

DMC provides additional graphics low-power idle states. It provides
capability to save and restore display registers across these
low-power states independently from the OS/Kernel.

This is the first release of DMC firmware for Broxton platforms.

GuC is designed to perform graphics workload scheduling on the various
graphics parallel engines. In this scheduling model, host software
submits work through one of the 256 graphics doorbells and this invokes
the scheduling operation on the appropriate graphics engine. Scheduling
operations include determining which workload to run next, submitting a
workload to a command streamer, pre-empting existing workloads running
on an engine, monitoring progress and notifying host SW when work is
done.

This is the first release of GuC firmware for Skylake platforms.
