[U-Boot-Users] SPD EEPROM Addresses on Ebony

Hello,

The u-boot/include/configs/ebony.h file has the following #defines (line 136):

#define CONFIG_SPD_EEPROM /* Use SPD EEPROM for setup */ #define SPD_EEPROM_ADDRESS {0x53,0x52} /* SPD i2c spd addresses */

The PPC440GP evaluation board user's manual says on Page 63 (also on Page 46) that the SPD EEPROM addresses are 0xA6, 0xA7 (for DIMM0) and 0xA4, 0xA5 (for DIMM1).

Why is there a difference between these addresses? Am I even looking at the right addresses or am I totally missing something?

Thanks, G.Sibi
