3feb9985a5 bcm2711/spi: Create interrupt-based SPI driver. 
This implements an interrupt-based SPI driver for the BCM2711 SPI
interfaces (excluding auxiliary SPI interfaces). Only tested on SPI0
since proprietary firmware does not initialize any other SPI interfaces,
and doing so will require reverse engineering.

e96fb6b118 arch/bcm2711, boards/raspberry-pi-4b: Add preliminary support for the BCM2711 and Raspberry Pi 4B. 
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.
