Yes, but I think what we most of all need is the i2c communication with the device. We should think about if the abstraction of the devices *behind* the bus brings us anything; note that you can do lots of things in scripts in u-boot-v2. Linke writing a shell function for your usb transceivers which just encapsulates the right predefined i2c_read/write operations. > Are we ok with i2ctools movement here? Hmm?
