[U-Boot] Usage of bi_env ?

[Dirk Behme <dirk.behme@googlemail.com>]

With U-Boot 2010.03 on an ARM board, the output of 'bdinfo' command gives:

...
env_t = 0x00000000
...

The code in common/cmd_bdinfo.c for this is

bd_t *bd = gd->bd;
...
print_num ("env_t", (ulong)bd->bi_env);

While checking if 0 for this value is correct or not, it looks to me 
that bi_env isn't set anywhere and is unused [1]. And it looks like 
bi_env is printed only in the ARM version of bdinfo. Do I miss 
anything here?

Best regards

Dirk
