Raspberry Pi/VPU

In order to use the mini UART, you need to configure the Raspberry Pi to use a fixed VPU core clock frequency. This is because the mini UART clock is linked to the VPU core clock, so that when the core clock frequency changes, the UART baud rate will also change. The enable_uart? and core_freq? settings can be added to config.txt to change the behaviour of the mini UART.
