[U-Boot] ENV library broken with setenv/printenv argument structs

Hi Andreas,

your series for the U-Boot environment tools does not let to use anymore the tools as library to be linked to custom program.

In fact, tools/env/Makefile generates a library too:

lib-y += fw_env.o \ crc32.o ctype.o linux_string.o \ env_attr.o env_flags.o aes.o

that means that fw_main should not maintain any structure that is referenced by the library. In fact, linking with the library (renamed as ibubootenv.a), gives the errors:

undefined reference to `printenv_args' undefined reference to `common_args'

The two functions fw_printenv() and fw_setenv() are then supposed to be called by a custom program, what it does not work anymore.

Can you take a look at it ?

Thanks, Stefano Babic
