- All our I2C components (RTC, ID EEPROM, DDR EEPROM) are connected to the
8560 CPM I2C controller, and not to the 8560 I2C controller. As far as I've seen, U-boot only supports the 8560 hardware I2C controller. Am I correct? If so, it seems that I can port the 82xx I2C driver (which is CPM based) to the 85xx without too much problems, and say add a CONFIG_CPM_I2C flag for this. Do you know if there's any planned support for this before I go ahead with this patch?
Why don't you simply use software (aka bitbanging) I2C? It's *much* easier, smaller, and more flexible.
- Our board can have up to two DDR modules, whose slots have different I2C
addresses. It seems that spd_sdram doesn't support this (as it only addresses one preconfigured I2C address). Questions are the same: Is this scenario supported in U-boot; If not - is there any planned support for it?
You add it?
