Add minimal device tree files for the core module and the development board. Support basic uart/gpio/dmac drivers, so supports booting to a basic shell. NOTE: the thead cpu reset dt-binding and DT node are removed in v3. This makes secondary CPUs unable to be online. However, minimal th1520 support is better than nothing. And the community has been working on and will work on the cpu reset dt-binding, for example, Conor, Guo and Jessica are discussing about it, I have seen valuable comments and inputs from them. I believe we can add back cpu reset in next development window. Thanks Since v2: - remove thead cpu-rst dt-binding doc and its DT node from th1520.dtsi - collect Reviewed-by and Acked-by tags - update uart reg size as suggested by Yixun - Add Guo Ren and Fu Wei as THEAD SoCs Maintainers Since v1: - add missing plic, clint, th1520 itself dt-bindings - use c900-plic - s/light/th1520 - add dt-binding for T-HEAD CPU reset - enable ARCH_THEAD in defconfig - fix all dtbs_check error/warning except the CPU RESET, see above.
