Its not clear to me why that should be the case when you also have: stdout-path = &scif2; Is this a baud issue? If so is it possible to set uboot to 115200 bps? This would be consistent with the way other boards are handled in mainline.

If it's not possible to update the bootloader, the other option is to use the console parametuers in stdout-path, e.g. stdout-path = "serial0:38400n8"; That way all the console stuff should get set up as expected without a command line being required. As far as I am aware, an explicit command line should then override this if necessary. Mark.

It's unlikely that there will be another board called "SILK", but it does make it hard for someone to get an idea of what the board is from the model string alone. Mark.

If there is a good motivation for a Renesas prefix then that is fine by me. But in that case it seems that it would be appropriate to update the existing renesas boards too. The only thing that stood out to me about "SILK" was that unlike other renesas boards names in .dtsi files it is all-capitals.
