Did you looked at the patches from Marcin. He also did such an
approach here:

[U-Boot,1/2] tools: env: Fix format warnings in debug
http://patchwork.ozlabs.org/patch/619306/

[U-Boot,2/2] tools: env: Add support for direct read/write UBI volumes
http://patchwork.ozlabs.org/patch/619305/

I like his approach more, as with it we can also use UBI Volumes
by name and the config file looks cleaner to me ...

bye,
Heiko
