SPDX-License-Identifier: GPL-2.0+ U-Boot for ODROID-N2/N2+ (S922X) ================================ ODROID-N2 and ODROID-N2+ are a Single Board Computers manufactured by Hardkernel with the following specifications: - Amlogic S922X ARM Cortex-A53 dual-core + Cortex-A73 quad-core SoC - 4GB DDR4 SDRAM - Gigabit Ethernet - HDMI 2.1 4K/60Hz display - 40-pin GPIO header - 4 x USB 3.0 Host, 1 x USB OTG - eMMC, microSD - Infrared receiver ODROID-N2+ uses Rev-C silicon allowing higher CPU opp-points. U-Boot contains logic to read the model detail from SARADC and select the correct device-tree file if FDTDIR is used instead of an FDT reference to a specfic device-tree.
