Thanks. AFAIK, this will not be used by any of the currently supported
boards. Is this correct?

Mauro is currently trying to port mainline U-Boot to the VoCore2 board
which also uses UART2. I did not look to close, but might this pin mux
option here be necessary for this VoCore2 board?

Thanks,
Stefan
