Hi,

It's not yet available in linux-firmware repository, but it is published
in the DRM staging repository [1].
The FW binaries can be found in the intel-staging branch [2].
It's still going through testing, but I expect that the merge request
will happen in the next couple of days.

Thanks,
-Michał
