[Sound-open-firmware] Signed firmware availability for kbl/cnl

Hi,

Thanks for all the hard work on SOF! We are hoping to try it on consumer products in order to support the internal digital mic, which is not supported when running in HDA mode.

Specifically Acer AIO Aspire Z24-890 (Intel i3-8100T) and ASUS MJ401TA (Intel m3-8100Y) are two models we have in hand right now.

I gather from previous discussions that even though the sof source code is public, the resultant binary files need to be signed by Intel before they can be used. Is that correct? If so, when will these be made available?

The files that Linux 5.2 is looking for here are: sof-cnl.ri sof-cnl-nocodec.tplg sof-kbl.ri sof-kbl-nocodec.tplg

Thanks
