No I'm not yet fed up :)

I'm still the same opinion like Ulrich, but unfortunately this is quite
a big change. But it should be possible to handle this without big
impacts on the "normal" application code (at least for the UART
drivers).

The bus architecture you implemented for SPI on the ARM architecture is
realy a big step forward and I think we should implement TWI/I2C the
same way.

Ulrich: Perhaps we could start into a discussion by a private
conversation? I think we should work on these changes in a development
branch. Might be good to have these changes for the 5.0 release?

Bye,

Ole
