You probably should fix this by making sure the device tree you're using has the appropriate stdout-path node. Because I think the functionality you're trying to use here is deprecated:
Hi Mark,
Interesting, I'll go with that approach instead.

A particular case that I'm dealing with is the default speed of 1500000 that the various Rockchip SoCs use. This doesn't work with many of the USB-to-serial interfaces on the market and is also rather susceptible to line noise. So for OpenBSD packages I've decide to use 115200 instead. But that means I have to patch all the device trees in addition to changing the CONFIG_BAUDRATE setting. If U-Boot would tweak the stdout-path property based on CONFIG_BAUDRATE that would make things easier.
That's an interesting use case! Would you mind testing this patch if possible?
Cheers,
