wanting to collect neat stuff to do from within u-boot on BBB

again, just for the sake of playing, i started a page listing what
one can do from within u-boot on the BBB so that students can stop in
u-boot and poke around to see what they can discover. here's the
simple stuff so far:

http://www.crashcourse.ca/wiki/index.php/U-Boot_Commands_on_the_BBB

and i now want to demonstrate the more involved commands like eeprom,
i2c, sf, spl and so on.

  if there are any useful pages on any of the remaining u-boot
commands worth stealing from, let me know, and i'll add that content.
