Today's Progress: Added basic support for STM32L4 family to the build system. Got a simple blinky test application working on a Nucleo-L476RG.
Things I've learned: The L4 family has two separate types of RAM which has to be factored in when generating the linker script.
Things I've planned for tomorrow: Either continue on the build-system or get back to the Spring application.
