This adds platform code for the Khadas VIM2 board based on a Meson GXM (S912) SoC with the Meson GXM configuration. This initial submission supports UART, MMC/SDCard and Ethernet. USB is partially supported. All the code is from Neil Armstrong! I just rebased the code, do some cleanup and tested on my board.
