The patch introduces a new family of SoCs based on STMicroelectronics'
STM32 MCU line. The patch introduces a basic arch/arm/soc layout along
with configuration of 2 MCUs from STM32F1 series: STM32F103VE and
STM32F103RB.
The patch assumes that other MCUs from STM32 family will be included
under arch/arm/soc/st_stm32 tree, to achieve the following layout:
arch/
arm/
soc/
st_stm32/
stm32f0/
stm32f1/
stm32f2/
...
stm32l0/
Most of the configuration within a single MCU family (ex. STM32F1) is
shared, however individual MCUs differ with respect to SRAM size, flash
size or the number of available peripherals. The patch assumes that per
MCU line Kconfig.soc.family file should introduce basic setup for given
series. This can be further tuned by per MCU files, with
Kconfig.soc.stm32f103rb and Kconfig.soc.stm32f103ve as examples.
Each family defines a configuration option, ex. CONFIG_STM32F10X, while
individual MCUs define a corresponding per MCU config options,
ex. CONFIG_STM32F103VE.
From the menuconfig perspective, the user is presented with a family
selection under General Platform Configuration/SoC Selection. A
specific MCU model can be selected by accessing General Platform
Configuration/STM32F1x MCU Selection, with the default entry being
selected by the board configuration.
