[U-Boot] [PATCH v2 0/3] Add set_env_soc_name() for STM32 SoCs

[patrice.chotard at st.com]

From: Patrice Chotard <patrice.chotard at st.com>

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()
