> This stuff is pretty ugly - would it not be better to make boards not define this in the CONFIG_SPL_BUILD case in the first place, rather than overriding them? As an example, I2C might be useful in SPL, but here it would be hard (or even uglier) to add.

That's what I had in previous versions of this series, but it seemed
even uglier, because it requires sprinkling "#ifndef CONFIG_SPL_BUILD"
through each of the tegra20 board configs.
