Need to quote the tested variable:
if test -z "${device}" ; then
setenv device mmc

Sounds good to me, though ${partition} would need to have an appropriate value
set in this case as well, as it currently uses ${mmcdev}:${mmcpart}. Not sure
how complicated it's worth making it...
Also looks like "Bootloader-Sets-Incorrect-Root: no" can be dropped entirely.
