Problem is, that those SPD values in this driver are board specific. Other 
boards with other DIMM(s) would need other EEPROM values. So it doesn't make 
sense to add this in such a common file for me. And I really don't like the 
name "dummy_i2c.c".

Which SDRAM controller is used on your 440/Virtex SoC? Is it an IBM compatible 
one? Or an IP core from Xilinx? I suggest you take a look at the similar 
implementation selectable via CFG_SIMULATE_SPD_EEPROM (used on bamboo).

Best regards,
Stefan
