Passing args to linux kernel is done by setting environment variable named=
=20
bootargs. If you can get the u-boot prompt it can be set like:
setenv bootargs parameters_go_here
you may want to save later this environment by issuing saveenv.
I don't have any u-boot device so can't tell you if that's working with=20
=46reeBSD but if it is please inform about it.
I've found that info on http://www.denx.de/wiki/view/DULG/UBootEnvVariables
