That's the full dance for getting it installed on a board it's not already
running on. Usually somebody else sets it up and you inherit one with a "tftp
download" script and another "boot from persistent storage" script and you
mostly just the command line to swap the autoboot variable to point to the right
one of the two.

The point of the tftp boot is quick reboot cycles during development, not having
to install the kernel you're booting on target each time. But as long as you're
not replacing u-boot and have a u-boot console you can fall back on an alternate
kernel from disk. (It's not really designed to give you a menu though, it gives
you a command line. You can have the kernel name to load in its own variable and
"set kernelname 'walrus.img'; run hdboot" though.)
There are probably more elegant ways to use this tool. I learned how to hammer
it in and get the lid off, and went on to other things...
