Hi all,
Wolfgang seems to think it's important:
Wolfram, please.

Ok, but that doesn't explain the reason. Wolfram, Paul, why do you
think this is needed ? Note that I am not opposed to adding spd
eeprom support, but I'd like to know why I am doing it before
I spend time on it.
A working eeprom driver is needed to get 'decode-dimms' from the
i2c-tools package working. Jean reported that EEPROM access for DDR5 is
different from DDR4, so it needs a separate driver. And
i2c_register_spd() then needs to be updated to use the new driver for
DDR5.
Well my original downstream driver already had eeprom access:

Yes, but you didn't send it upstream, so I took it, fixed a couple of bugs,
And I appreciate that!
dropped eeprom support since that is secondary for my use case as well as the
I only said the original code had this implemented if someone wants to re-add it
to save them some time not having to re-write it from scratch ;-)
That is for sure what I had planned to do.
out-of-tree parity code, and submitted it. I'd be more than happy to let you
take over if you like.
I’m mostly out of time, so I appreciate you starting the upstream process.
Ok, I'll keep going.
Thanks,
Guenter
