[U-Boot] [PATCH v3 0/9] Improve rockusb support in U-Boot

[Alberto Panizzo]

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

Changes in v2:
- Reworked patch 1/8 to obtain simpler and more logical code
- Rewrote some patch messages
- Updated documentation in README.rockusb  patch by patch
- Added patch 8/8 to fix debug prints of original code

Changes in v3:
- Removed magic block size of 512 bytes for all implemented commands
  original behavior of re-probing a non present block device
  (like a non plugged SD-Card) is kept
