Hm... Please keep in mind that DFU support is supposed to be
completely hardware independent - it should not only work on AT91
systems, and not even be restricted to ARM, but instead be usabel on
all architectures and boards.

I'm not sure what you mean by "full diff". If you think about posting
all your changes in a single patch, then please don't.  You have to
split the stuff into independent parts - DFU support is then just one
patch in your patch series.

Thn it is all the more important to correctly split your changes into
independent (orthogonal) patches.
