Hi Marek,
Dear Lukasz Majewski,
Those patches add support for composite USB download gadget. This gadget (at least for now) is equipped with DFU download function.
A separate DFU back-end and front-end have been added. Back-end is placed at ./drivers/dfu directory. The front-end is implemented as USB function.
The back-end is written in a generic manner with storage device specific code separated (eMMC).
DFU specification can be found at: http://wiki.openmoko.org/wiki/USB_DFU_-_The_USB_Device_Firmware_Upgrade_sta ndard

will we see a next version of this series please?
I've just come back from my holiday. I will continue work on this.
Or where did the discussion get?
As fair as I remember, the discussion ended up with a conclusion, that new layer of abstraction (in a form of function call) is needed.
I will rehack the cmd_mmc.c to include new functions in it. It will be a prepatch for the DFU.
