Thank you so much for the new version! I would really like to include
this in the next i2c-tools version, hopefully this year. This is the
last "blocker". But being zero familiar with the topic, I really need
help. Reviews would be most awesome, of course. But if nobody has time
for that, test reports would also be super helpful. Sadly, I don't even
have DDR5 here.

So, anyone interested in helping?

Happy hacking,
