Commit be72591bcd64 ("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.

Using optimized versions of memset and memcpy from linux brings a quite
noticeable speed (x2 or better) improvement for these two functions.

This helps to clean up the include/ directory so that it only contains
non-architecture-specific headers and also matches Linux's directory
layout which many U-Boot developers are already familiar with.
