The Pine64 Quartz64 Model B is a credit-card sized single-board
computer based on the Rockchip RK3566 SoC. The board features an M.2
PCIe slot, USB3, USB2, eMMC, SD, ethernet, HDMI, analog audio out, a
40 pin GPIO header and a DSI and CSI port, as well as on-board Wi-Fi.

Features tested on a Quartz64-B 4GB v1.4 2022-06-06:
- SD-card boot
- eMMC boot
- SPI Flash boot
- PCIe/NVMe
- USB host

Device tree is imported from linux v6.4.
