Hi Alberto, Thanks for your patches, and I'm so glad for people using rockusb and try to improve it.
You can reference to rockchip source code here: https://github.com/rockchip-linux/u-boot/blob/release/drivers/usb/gadget/f_rockusb.c We use msc as base framework instead of dfu because of the big performance improvement, and the cmd handling part will be the same. PS: Yes, rockusb is available for all Rockchip's SoCs.
