What Juergen meant to say is "register partitions named env0, env1, ...". The
barebox startup code then automatically picks the first valid environment
partition.
To register partitions (with bad blocks awareness) use devfs_add_partition()
and then dev_add_bb_dev(). grep for "env0" under arch/ for many examples.
