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.
