U-boot contains a small shell, when you print all of the environment variables, you are reading shell scripting.

I checked again, and it seems that you're right. The correct format seems to be:

setenv bootargs $bootargs init=/bin/sh
boot

And for testing purpose:

exec init

from here:

There are more complex usages that I don't want to test initially!

Btw, the original init was this (see page 3 for the logs from the initial state):

/sbin/init.sysvinit
