Includes a Mini-UART NSH console for the 4B, tested on the 4GB RAM model. Part of an I2C driver which can only read, boiler-plate for a SPI driver, and a GPIO driver with limited pins. Some tools are present for automatically fetching the boot files and creating the `config.txt` file based on selected Kconfig options.
