Commitbe72591bcd("Kconfig: Move USE_ARCH_MEMCPY/MEMSET to Kconfig") is misconversion. The original logic in include/configs/uniphier.h was as follows: #if !defined(CONFIG_SPL_BUILD) && !defined(CONFIG_ARM64) #define CONFIG_USE_ARCH_MEMSET #define CONFIG_USE_ARCH_MEMCPY #endif This means those configs were enabled when building U-Boot proper, but disabled when building SPL. Likewise for Tegra. Now "depends on !SPL" prevents any boards with SPL support from reaching these options. This changed the behavior for UniPhier and Tegra SoC family. Please notice these two options only control the U-Boot proper build. As you see arch/arm/Makefile, ARM-specific memset/memcpy are never compiled for SPL. So, __HAVE_ARCH_MEMCPY/MEMSET should not set for SPL.
