This is a port of NuttX to the STM32L4 Family
Used development boards are the Nucleo L476RG, Nucleo L496ZG,
Nucleo L452RE and STM32L4VGDiscovery.
Nucleo L452RE, Nucleo L432KC, STM32L4VG Discovery and
Motorola MDK.
Most code is copied and adapted from the STM32 and STM32F7 ports.
The various supported STM32L4 families are:
-------------------------------------------------------------
