#Minimal MCU init for STM32F407xx
Pretty much a copy/paste of the STM32F4-Discovery template from ST. It seems general for the MCU. However main.h/.c were renamed to mcu_init.h/.c, since it felt like a cleaner structure.
This whole directory will be compiled and linked to the application, that will
typically invoke mcu_init() as its first invokation in main(). This
directory will also belong to the include directories for the application.
