* Introducing Rockchip rk322x SoC support Main features: - Legacy kernel flavour based upon stable v2.x rk3288 Rockchip branch (https://github.com/rockchip-linux/kernel/tree/stable-4.4-rk3288-linux-v2.x) - Current kernel flavour based on mainline 5.6.y kernel - Mainline u-boot (v2020.04) - Single generic tv box target (rk322x-box) which boots on all the known tv boxes - Hardware devices (eMMC/NAND, led wiring configuration, SoC variant selection) modulation done by user at runtime via device tree overlays - a script (rk322x-config) is provided for autodetection and simple configuration by inexperienced users; - Bits added to armbian-hardware-optimization to set affinity for irq handlers - rk322x-box targets already added to targets.conf for automatic image creation * Removed disabled patches * Restored mysteriously removed comment character
