Inès Varhol 41581f1361 hw/arm: Add minimal support for the B-L475E-IOT01A board
This commit adds a new B-L475E-IOT01A board using the STM32L475VG SoC
as well as a dedicated documentation file.
The implementation is derived from the Netduino Plus 2 machine.
There are no peripherals implemented yet, only memory regions.

STMicroelectronics STM32 boards (``netduino2``, ``netduinoplus2``, ``stm32vldiscovery``)
========================================================================================
The `STM32`_ chips are a family of 32-bit ARM-based microcontroller by
STMicroelectronics.
.. _STM32: https://www.st.com/en/microcontrollers-microprocessors/stm32-32-bit-arm-cortex-mcus.html
The STM32F1 series is based on ARM Cortex-M3 core. The following machines are
based on this chip :
- ``stm32vldiscovery`` STM32VLDISCOVERY board with STM32F100RBT6 microcontroller
The STM32F2 series is based on ARM Cortex-M3 core. The following machines are
based on this chip :
- ``netduino2`` Netduino 2 board with STM32F205RFT6 microcontroller
The STM32F4 series is based on ARM Cortex-M4F core, as well as the STM32L4
ultra-low-power series. The STM32F4 series is pin-to-pin compatible with STM32F2 series.
The following machines are based on this ARM Cortex-M4F chip :
- ``netduinoplus2`` Netduino Plus 2 board with STM32F405RGT6 microcontroller
- ``olimex-stm32-h405`` Olimex STM32 H405 board with STM32F405RGT6 microcontroller
- ``b-l475e-iot01a`` :doc:`B-L475E-IOT01A IoT Node </system/arm/b-l475e-iot01a>` board with STM32L475VG microcontroller
There are many other STM32 series that are currently not supported by QEMU.
