It's arelady there. > But in the docs it says it's only for SOFT_I2C aka bitbang! Right, because you cannot toogle the pins at your liking with the CPM's I2C controller. > a) can I toggle the pins using GPIO and still use HARD_I2C? or Yes, you can. But this has not been implemented yet. And if you do, you will find you have copied 90% of the soft_i2c driver so why not use this from the beginning? Using HARD_I2C has _zero_ advantage for U-Boot. > b) can I use SOFT_I2C in PPCBoot and CPM I2C (8xx-algo) under linux? Yes, you can.
