This rewrite uses lately promoted eeprom_init(int) function to choose the right I2C bus when writing data to the EEPROM.

Hi Marek,
works this for you? I can't kill the i2c_read() cause eeprom_read() will blow up my SPL size. While you are on it, there are some other eeprom implementations (freescale) not yet covered by your removal.
regards
