What is the role of Configuration EEPROM on Blaze MDP?

Hi Champs,

I'm checking the Blaze MDP application board schematics (750-9012-109-SCH Rev.A) and found a component "Configuration EEPROM (U49: CAT24C208WI-G)" on page  4.

So, Could you please let me know the role of the component.  I could not find any descriptins of it in the schematics and Blaze Users Guide.

Thanks in advance for your cooperation.

Best regards,
j-breeze

    I have found this so far,

    http://git.omapzoom.org/?p=repo/u-boot.git;a=blob;f=cpu/omap4/sys_info.c;h=ba5203f430eecef0712838d5f775794ecb266c30;hb=91cb84ab3f6fce72d1d9b8a9804710b6907af350

    /*******************************************************************

    The chip is a Eeprom with dual interface, but it is one memory space.

    I am not sure that discussing Blaze schematics is allowed in public forums, but have you tried to ask TI representative about this information?
