Thanks Arnd, do you mind sharing your config?

https://pastebin.com/HRX5xi3R

will give it a try, thanks!

We noticed last week that
there's a depend/select confusion might be simpler to fix, see
https://github.com/thesofproject/linux/pull/2047/commits

If I look at the first line I see a IMX_DSP=n which looks exactly like
what we wanted to fix.

Yes, I think that fix addresses the build warning as well, but looking
more closely I don't think it's what you want: If you do this on
a config that has the IMX_DSP disabled, it would appear to the
user that you have enabled the drivers, but the actual code is still
disabled.

Are you sure? we added a select IMX_DSP, so not sure how it can be disabled?

I just tested Arnd's config with the patch we came up with for SOF (attached) and it makes the unmet dependency go away and builds fine. the problem is really using select IMX_DSP if it can be disabled by something else. My proposal looks simpler but I will agree it's not necessarily super elegant to move the dependency on IMX_BOX into SOF, so no sustained objection from me on Arnd's proposal.

Daniel, this is your part of SOF, please chime in.

Thanks
