u-boot : CNFIG_SPL_BUILD is not in Kconfig

[安保.1]

There is a'ifdef CONFIG_SPL_BUILD' in stm32mp1.h, Makefile or many files, but there is no setting in the Kconfig file.

Hello @安部 �?​  ,

I don't know which version of the ecosystem you are using, but since ecosystem V2.0, "basic boot" is no longer supported. Uboot SPL can no longer boot the kernel.

Cf https://wiki.st.com/stm32mpu/wiki/STM32_MPU_ecosystem_release_note_-_v4.0.0#OpenSTLinux_-28Cortex-C2-AE-A7-29

And can no more be generated since V4.0.0:

If you were trying to use the DDR Tuning tools, you must now use the dedicated tool "STM32DDRFW-UTIL" :
