Dear Simon Glass,

As mentioned before, this is what we currently have as "device model"
in U-Boot - not only I2C: we have the same "current device" concept
with IDE, USB, ...

It makes no sense trying to change it here; it would only cause even
more incompatibilities.  If you want to fix that, then help working on
the new driver model.  Marek is planning for this.

Best regards,

Wolfgang Denk
