Dear Heiko Schocher,

I'm not surprised...
So, it seems to me, that, if SPI is enabled, it is not possible to use an I2C EEprom with an address != 0, because in common/env_eeprom.c @line79 in env_init():
Actually you are most probably not supposed to use any I2C EEPROM at all.
I tried to use "git blame" to find out where this comes from, but this is in code since the "initial revision" ... so I ask here on the mailinglist, if somebody knows, if this is a feature or a bug?
I think this is a deficiency of the original implementation which assumed that if there was an EEPROM, it was either attached to the I2C or to the SPI bus, and that SPI would never be used in U-Boot for anything else than reading an EEPROM.
Please consider it a bug...
Best regards,
