Hello Bruno,
 
> Yes, use the same U-Boot package for both bootloader and tools.

> 2) fw_printenv/fw_setenv support both storage technologies:

As long as there is only one device for your platform, we should try to use the install_alternative method to install
a project specific /etc/fw_env.config from <BSP>/projectroot. If there are multiple locations for the environment a project specific way to set a link to the config file to be used has to be implemented in the root FS
