part of what i'd like to do is document the u-boot instructions that
one can use to poke around the beagleboard before even booting beyond
that, since inordinately curious people might want to play with u-boot
to inspect the HW characteristics of the board.
for example, say someone is curious about I2C:
i'm about to run through the possibilities, and i'm open to
suggestions as to what instructions folks have found useful to snoop.
i might put up a list like that on my wiki just for fun.
