I didn't found any datasheet without the CMP bit, but now that I know
these chips had a new batch (with mandatory SFDP support) starting from
2016, whereas the datasheets I looked at were from 2017, it is possible
that I couldn't find an old enough one.
Which brings me to a more important question: can we anyway enable CMP
anyway? I contributed several patches for that already (merged). I guess
if the CMP bit is not present, the old software does not use it. If it
tries to use it, normally the verification should fail.
Thanks,
Miquèl
