Nothing of the above is really fundamental. Without serial drivers you
won't see anything of course, but this won't stop barebox from working.
I think this only reflects a change of taste during time and should be
done consistently so that other people know how to do it. Prefered is
the obj-$(CONFIG_SPI) += spi/ style.
