I'll submit a v4.

Indeed it is likely to be FAQ of the month, especially if it lands in
the next software update that gets shipped with the board.  It is a
case, however, in which I like the answer--no more need to run
mkimage.  The conversion process of a boot.scr script (commands) to a
uEnv.txt file (variable setting) won't be exactly trivial, so that has
me a tiny bit concerned.  Still, most cases will be solved by a *much*
simpler uEnv.txt script and an overall simpler process.

I still see a need to use the USER button to go into some sort of
fall-back state to ignore this file and boot some sort of recovery
image.  Since that code isn't upstream yet, there is still going to be
some delta between upstream and what ships on the board--unless I can
somehow figure out an easy way to get a command added for the generic
gpio framework.
