AFAIK that's mostly about modifying an in memory FDT, but it doesn't
actual deal with passing it to the kernel, which is done by passing the
address as the third argument to bootm or bootz.

You need to tell it to pass it to the kernel as above, yes. But for most
platforms u-boot itself doesn't use (i.e. consume for its own hardware
detection purposes) the fdt apart from that.
