Hi Simon et al,
(Resend to include u-boot mailing list)
I'm in the process of converting Kirkwood boards to use DM SERIAL. I could not seem to get it to work, having tried adding CONFIG_DM_SERIAL, and also playing with various related CONFIG options (CONFIG_SPECIFY_CONSOLE_INDEX and CONFIG_CONS_INDEX ). From my reading various board configurations that were already converted to DM_SERIAL, I'm under the impression that just turning on CONFIG_DM_SERIAL would work without any other addition.
The board I'm testing is Zyxel NSA310S Kirkwood 6702 (6192) SoC.

I also added kirkwood-nsa310s-u-boot.dtsi to help in running kwboot.
&uart0 { u-boot,dm-pre-reloc; };
I've tried kwboot the new u-boot image, and also flashed this image to NAND, and in both cases, I got a silent serial console. It seems to hang up right off the bat. Hope you can help by giving me some pointers on how to debug this.
Thanks, Tony
