CONFIG_USE_ARCH_MEMSET controls nothing about SPL. (it is effective only on U-Boot proper building of ARM).
That's not true. We have these functions available to SPL and use them there by default now (as it's a speed win and we want out of SPL ASAP).
This is not clear to me.
How can you make the optimized memset available to SPL?
As far as see arch/arm/lib/Makefile, memset.o is only compiled (if CONFIG_USE_ARCH_MEMSET is defined) for the U-Boot full image.
ifndef CONFIG_SPL_BUILD ifdef CONFIG_ARM64 obj-y += relocate_64.o else obj-y += relocate.o endif
obj-$(CONFIG_CPU_V7M) += cmd_boot.o obj-$(CONFIG_OF_LIBFDT) += bootm-fdt.o obj-$(CONFIG_CMD_BOOTI) += bootm.o obj-$(CONFIG_CMD_BOOTM) += bootm.o obj-$(CONFIG_CMD_BOOTZ) += bootm.o zimage.o obj-$(CONFIG_SYS_L2_PL310) += cache-pl310.o obj-$(CONFIG_USE_ARCH_MEMSET) += memset.o obj-$(CONFIG_USE_ARCH_MEMCPY) += memcpy.o else obj-$(CONFIG_SPL_FRAMEWORK) += spl.o obj-$(CONFIG_SPL_FRAMEWORK) += zimage.o endif
