This depends on where you want to include it. I think it is obvious
that SA applications require a substantial amount of U-Boot
infrastructure to be running. By design, they are intended to be
called only when any other interactive command can be exectuted. If
you know exactly what you are doing, you may run them a little
earlier, but probbaly not much.
Me recommendation is: if you want to run SA applications early, you
can do this from the "preboot" hook. Any earlier point may or may not
work, and especially there is no guarantee that this will not break
in any future versions of U-Boot.
Keep in mind what SA applications are used for - especailly, they are
NOT intended to sneak in propriatary initialization code in early
boot stages, and this is about the only reason I can imagine to use
them in that early.
Best regards,
Wolfgang Denk
