Actually, I didn't finished this at all. It is possible to do this 
manually at prompt by "setenv dfu_alt_info ${dfu_alt_bootloader}",
but this overwrites current alt settings, so it's not so good.

In the next patch set I will add some feature to DFU, since 
"dfu_alt_bootloader" could be treat as one of DFU option.

Thank you again,
