rockusb protocol has been introduced by Eddie Cai in U-Boot mainline
allowing to write internal eMMC of RK3288 based boards (and potentially
all other Rockchip's CPUs).

On workstation side the open source project rkdeveloptool do implement
the rockusb protocol. You can find it on GitHub here:
https://github.com/rockchip-linux/rkdeveloptool

This patchset increase the supported functionalities on target side
allowing developers to:
- Read flash: rl command of rkdeveloptool
- Read chip version: rci command of rkdeveloptool
- Complete the write cycle implementing block erase
- Improve read/write speed

Alberto Panizzo (7):
usb: rockchip: fix command failed on host side due to missing data
usb: rockchip: implement skeleton for K_FW_GET_CHIP_VER command
rockchip: rk3288: implement reading chip version from bootrom code
usb: rockchip: implement K_FW_LBA_READ_10 command
usb: rockchip: implement K_FW_LBA_ERASE_10 command
usb: rockchip: be quiet on serial port while transferring data
usb: rockchip: boost up write speed from 4MB/s to 15MB/s
