One difference at the moment is that byt-rt5640 machines out there have differences in audio routings but those are not too difficult to handle in the same machine driver.
Bigger question how to handle platform part? I.e. can these use the same drivers and ADSP firmware? If they can, is the firmware available for distributions to take?
The two firmware are *not* compatible and that is the big reason why we can't reuse the parts available
Ok, so firmware appears to works on other than CR Baytrails too. Is it available in linux-firmware since if it's not when changing the platform drivers there will be obvious regressions to users?
Can we take a step back here: what are the firmwares and hardware platforms we're talking about here?
Yes, I have tested this one on T100 and doesn't seem to break anything. Please do test and revert if you find issues on any other available board (I don't have any other board)
Well, those audio routing differences require to have DMI quirks. E.g. T100 has analogue internal mic, Dell Venue 8 Pro 5830 has digital mic connected to DMIC2 of the RT564x and some have it connected to DMIC1.
Are any of these things on sale at the minute? Looks like T100 and the Dell both are but I'm not sure if they're current or previous models.
