Hi Rob Herring,
I am just do a function testing on Atmel sama5d3xek board. And a small
comment as following.
Btw, do you test to transfer big size file. I try a file bigger than
100MiB, it will hang. However use DFU or RNDIS don't meet this issue.
How much RAM do you have? It will happily download into the end of RAM
overwriting u-boot if loadsize is not set. DFU at least has its own
buffer size configuration.
There are 512MiB RAM on board. So, it won't be a problem to load this
file from the begin of the RAM (As the u-boot is relocated to top RAM).

Do this only in unbind, as unbind is really disconnect.
So, what should disconnect function do?
Maybe some misunderstanding. I mean the "gadget_is_connected" should be
cleared in unbind function while not in disconnect function.
