Maybe a better way is to use CONFIG_PREBOOT as you do, but without
hard-coding the variable. You can add "preboot" to the default
environment (CONFIG_EXTRA_ENV_SETTINGS), and the user can still
overwrite the behavior setting the variable in the u-boot shell.

But I see I did not follow the same approach for the mx51evk (blame on
me !).
