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.

B-L475E-IOT01A IoT Node (``b-l475e-iot01a``)
============================================
The B-L475E-IOT01A IoT Node uses the STM32L475VG SoC which is based on
ARM Cortex-M4F core. It is part of STMicroelectronics
:doc:`STM32 boards </system/arm/stm32>` and more specifically the STM32L4
ultra-low power series. The STM32L4x5 chip runs at up to 80 MHz and
integrates 128 KiB of SRAM and up to 1MiB of Flash. The B-L475E-IOT01A board
namely features 64 Mibit QSPI Flash, BT, WiFi and RF connectivity,
USART, I2C, SPI, CAN and USB OTG, as well as a variety of sensors.
Supported devices
"""""""""""""""""
Currently, B-L475E-IOT01A machine's implementation is minimal,
it only supports the following device:
- Cortex-M4F based STM32L4x5 SoC
Missing devices
"""""""""""""""
The B-L475E-IOT01A does *not* support the following devices:
- Extended interrupts and events controller (EXTI)
- Reset and clock control (RCC)
- Serial ports (UART)
- System configuration controller (SYSCFG)
- General-purpose I/Os (GPIO)
- Analog to Digital Converter (ADC)
- SPI controller
- Timer controller (TIMER)
See the complete list of unimplemented peripheral devices
in the STM32L4x5 module : ``./hw/arm/stm32l4x5_soc.c``
Boot options
""""""""""""
The B-L475E-IOT01A machine can be started using the ``-kernel``
option to load a firmware. Example:
.. code-block:: bash
$ qemu-system-arm -M b-l475e-iot01a -kernel firmware.bin
