I don't think printing the programming time/speed at beginning of the
operation is doable. At least not without bigger changes. But an output at
end of the operation like:

Wrote 512kB in 5.4 seconds (94,8 kB/s)

would be nice. This way the developer could see, if the interface to the FLASH
chips is optimized. But I think this is overkill too. Let's concentrate on a
clean progress bar with a fixed length.

Patches welcome. :)

Stefan
