+Subject: [PATCH] arm64: dts: rockchip: Add Radxa ROCK 2A/2F
+
+The ROCK 2A and ROCK 2F is a high-performance single board computer
+developed by Radxa, based on the Rockchip RK3528A SoC.
+
+Add initial device tree for the Radxa ROCK 2A and ROCK 2F boards.
+

+Subject: [PATCH] board: rockchip: Add Radxa ROCK 2A/2F
+
+The ROCK 2 Family is a high-performance SBC (Single Board Computer)
+developed by Radxa, based on the Rockchip RK3528A.
+
+The Radxa E20C shares some board characteristics with the ROCK 2 family
+boards.
+
+Add support for the ROCK 2A and 2F boards. The radxa-e20c-rk3528 target
+is also extended to support booting ROCK 2 boards.
+
+Features tested on a ROCK 2A v1.202:
+- SD-card boot
+- Ethernet
+- USB host (with pending DT changes)
+
+Features tested on a ROCK 2F v1.016:
+- SD-card boot
+- eMMC boot
+- USB host (with pending DT changes)
