With this Command it is possible to add new I2C Busses, which are behind 1 .. n I2C Muxes. Details see README.
While this is pretty cool, I'm curious what circumstances lead to needing to add I2C buses at run-time via command line. Presumably you have a real business need for this in a bootloader?
Yes. This boardmanufacturer has a lot of hardwareversions with different I2C bus wirings, but has for example always one EEProm with configdata. Now, he can use one u-boot image for all this boards and has just to define in the environment, in which way he can reach this EEprom.

Interesting. Thank you.
