This patch enables the use of the optimized memset(), memmove() & memcpy() versions recently added on ARM64.
Signed-off-by: Stefan Roese sr@denx.de
Changes in v5:
- memmove is now auto-selected (or deselected) with the memcpy Kconfig selection as it's entry is the same as memcpy for ARM64
Changes in v3:
- Add memmove as well
