Subject: [U-Boot] Very confusing variable=name behaviour

Hi!

I'm getting quite crazy behaviour of variables in recent u-boot:

VERSION = 2016
PATCHLEVEL = 01
SUBLEVEL =
EXTRAVERSION = -rc1


Bytes transferred = 104656 (198d0 hex)
=> bootm_boot_mode=nonsec
=> echo $bootm_boot_mode
nonsec
=> prinetenv bootm_boot_mode
Unknown command 'prinetenv' - try 'help'
=> printenv bootm_boot_mode
## Error: "bootm_boot_mode" not defined
=> echo $bootm_boot_mode
nonsec
=>

What is going on there? C-level  "getenv" fails on such variable, too.

bootm_boot_mode = '<NULL>'

Explicit setenv behaves as expected:

=> setenv bootm_boot_mode nonsec
=> echo $bootm_boot_mode
nonsec
=> printenv bootm_boot_mode
bootm_boot_mode=nonsec
=>

Best regards,
