Heiko, what am I missing here? I thought any reference to environment pollution in the form of "dtt_bus" would have been gone by now. Did we misunderstand each other here? If its value changes between boards
Yes, I think so ...
(and not boots), then there is no reason for this to be an environment variable. No?
There is a reason, because if it is an environment variable, we (or better the board manufacturer) can use one u-boot binary for all variants of his hardware (as I said, they differ only in the i2c bus topology)
