Subject: ARM: revive CONFIG_USE_ARCH_MEMCPY/MEMSET for UniPhier and Tegra
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=085be482f6c62614ddbe51000a09db9dec360e90;p=u-boot.git

ARM: revive CONFIG_USE_ARCH_MEMCPY/MEMSET for UniPhier and Tegra

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.

Fixes: be72591bcd64 ("Kconfig: Move USE_ARCH_MEMCPY/MEMSET to Kconfig")
