Not sure if this is all right (all show the barebox partition):

Okay, 256 kiB
> crw------- 0 self0
Hmm, 0?
> crw------- 262144 nand0.barebox
Okay, 256 kiB
> crw------- 0 nand0.barebox.bb
Again, 0?
For the environment it looks different:
> crw------- 131072 env_raw
> crw------- 131072 env0
> crw------- 131072 nand0.bareboxenv
> crw------- 131072 nand0.bareboxenv.bb
All are 128 kiB.
