Great, thanks for tracking that down. It's a bit odd that DEBUG_LL_UART_NONE fails (after all it should be doing nothing) but given that this flavour supports a single SOC which all have the same UART (AFAICT, it's on in upstream orion5x defconfig at least) I think there's no reason not to do this. When I tried this I also got CONFIG_DEBUG_ICEDCC coming on. From the Kconfig help I don't think we want this at all ("Note that the system will appear to hang during boot if there is nothing connected to read from the DCC.") so I have disabled it. Please let me know if you think we want this for some reason. I'll kick off a local build with this in now and push once it's done. (I'm away this w/e, so might be next week) Ian.
