The NanoPi R2S does not have a board specific MAC address written inside
e.g. an EEPROM, hence why it is randomly generated on first boot.
The issue with that however is the lack of a driver for the PRNG.
It often results to the same MAC address used on multiple boards by
default, as urngd is not active at this early stage resulting in low
available entropy.
There is however a semi-unique identifier available to us, which is the
CID of the used SD card. It is unique to each SD card, hence we can use
it to generate the MAC address used for LAN and WAN.

Hardware
--------
RockChip RK3328 ARM64 (4 cores)
1GB DDR4 RAM
2x 1000 Base-T
3 LEDs (LAN / WAN / SYS)
1 Button (Reset)
Micro-SD slot
USB 2.0 Port
Installation
------------
Uncompress the OpenWrt sysupgrade and write it to a micro SD card using
dd.
MAC-address
-----------
The vendor code supports reading a MAC address from an EEPROM connected
via i2c0 of the SoC. The EEPROM (address 0x51) should contain the MAC
address in binary at offset 0xfa. However, my two units didn't come with
such an EEPROM soldered on. The EEPROM should be placed between the SoC
and the GPIO pins on the board. (U10)
Generating rendom MAC addresses works around this issue. Otherwise, all
boards running the same image have identical MAC addresses.

This adds the new rockchip target and support for RockPro64 RK3399
Flash: 16 MiB SPI NOR
RAM: 2 GiB/4 GiB LPDDR4
SoC: RK3399
USB: 2x USB 2.0, 1x USB 3.0, 1x USB-C
Ethernet: 1x GbE
PCIe: PCIe 2.0, 4 lanes
Storage: eMMC or SD card
Optional SDIO wifi/bt module
The Pine64 RockPro64 is a single-board-computer with a 4x PCIe connector,
6 ARM64 cores (4 little, 2 big), plenty of RAM and storage.
By default the single Gigabit-Ethernet port is configured as the
LAN port.
Installation of the firware is possible by dd'ing the image
to an SD card or the eMMC flash.
Serial: 3v3 1500000 8n1
U-boot is build from the mainline tree and
integrated into the images. Required ATF to build u-boot
is downloaded from a CI build bot.
