Hi Marek,
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_stan...
Example usage:
u-boot side: dfu mmc 0 PC: dfu-util -U IMAGE.bin -a uImage (for upload) dfu-util -D uImage -a uImage (download)
To list the alt settings: dfu mmc 0 list
Test HW: Exynos4210 Trats board

Do you have more comments about those patches?
I _think_ he's been busy with exams and preparing for the U-Boot BoF this week. I'll make sure this gets brought up then however.
