eeprom kernel module removed in 6.7

The (legacy) kernel module eeprom was removed from Arch's linux config with 6.7:
https://gitlab.archlinux.org/archlinux/ … _2676_2689

Is there a reason for this?

I was able to use decode-dimms with this module to get intel on the RAM timings etc., the other modules the tool suggests don't work for me.

Could this one be re-enabled?

I see, hopefully the i2c-tools will be able to work with some other module some time, I guess.

So this don't work for you?:

udevadm info -e | grep -e MEMORY_DEVICE -e MEMORY_ARRAY
sudo dmidecode -t memory

@loqs:
Yeah the at24 module won't work on my main rig, loading the i2c-dev module worked on my thinkpad work laptop for decode-dimms, but not on my main rig either. Seems like a stub, having to dive deep after removing that legacy eeprom that just worked.
decode-dimms doesn't even seem to work with eeprom SPD dumps with the -x/-X commands, throws some arbitrary error.

@xerxes_:
This gets some basic info on the RAM modules, yes, but not the full information of the serial presence detect (SPD), like default timings etc.
