From: Fabio Estevam <redacted> The Onion Omega4 Evaluation Board is based on the Omega4 SoM and has: - 256 MB of RAM - 256 MB of SPI-NAND - Ethernet - USB OTG - Wifi - SD card - Camera connector The details can be found at: https://documentation.onioniot.com/omega4/getting-started/ Add the initial support for this board so that it can fully boot into Linux with the root file system stored in the SPI NAND. Signed-off-by: Fabio Estevam <redacted> --- Changes since v3: - Split into SoM and base board. arch/arm/boot/dts/rockchip/Makefile | 1 + .../boot/dts/rockchip/rv1103b-omega4-evb.dts | 55 ++++++++++++++++ .../arm/boot/dts/rockchip/rv1103b-omega4.dtsi | 65 +++++++++++++++++++ 3 files changed, 121 insertions(+) create mode 100644 arch/arm/boot/dts/rockchip/rv1103b-omega4-evb.dts create mode 100644 arch/arm/boot/dts/rockchip/rv1103b-omega4.dtsi
