Hi
This series will be abandoned and replaced by a new patch using CONFIG_ENV_VARS_UBOOT_CONFIG flag.

This series allows to create and set the environment variable "soc_name" corresponding to the current STM32 SoCs name.
We will add STM32 SoCs support in buildroot environment Our objective is to propose a flexible solution to boot linux kernel from sdcard.
As for STM32F4, STM32F7 and STM32H7 linux defconfig is slightly different (specific CONFIG_DRAM_BASE and CONFIG_DRAM_SIZE) we can't use the same zImage for all these SoCs.
To simplify, we will embed all dtb/zImage in the sdcard and using the soc_name environment variable to select the correct zImage.
v2: _ Remove get_cpu_id() function and use directly CONFIG_STM32xx flag to identify the STM32 SoC family.
Patrice Chotard (8): mach-stm32: Add get_cpu_id support mach-stm32: Move BOARD_LATE_INIT flag to mach-stm32 Kconfig board: stm32: Add set_env_soc_name() in board_late_init()
