Can I suggest that instead of using boot.scr files we just use a text
file that can be imported to the environment and a command run?  The
omap3_beagle example (uEnv.txt + uenvcmd) is something I plan to
propogate to more TI boards and I think it'd be good if we picked it up
on other SoCs.  Or came up with a better plan for everyone :)  The main
benefit of uEnv.txt over boot.scr is that it's now plain text, rather
than text that needs to be mkimage'd at each change.
