What purpose this IC(eeprom)?

[김유석]

Dear Sir.

MY EVB is ADI SG-2440.

I was found some eeprom on my evb.

This eeprom(CAT24C0EYI-GT3) is store the config of SDRAM. *I gu**ess.*

So, I was search ADDR 0xA0 and procedure of config for sdram from 
coreboot source tree.

But can't found hands on ADDR 0xA0 and found the some structure for 
config of sdram, but not used this strcture.

Could you explain to me that "*Role of this eeprom*".

Thank you.

Given its name (SPD) it sure seems like SPD.

As to your not being able to address it, a lot of times this can happen if
there is an SMBUS mux on the board and it's not set up on POR so you can
see that device.
