AFAIK, the U-Boot configuration doesn't affect the userspace fw_env
tools, so auto size has to be opt-in separately in fw_env.config, which
is where I did use 0 to mean auto (see the referenced commit
e282c422e0). You should be able to test that part already with just
fw_setenv built from master and an appropriate fw_env.config [or perhaps
you need to add another "mtdinfo.type == ..." condition first].
