For 64-bit ARM SoCs we rely on non-U-Boot code to bring up the CPU in AArch64 mode so that we don't need the SPL. Non-cached memory is not implemented (yet) for 64-bit ARM.
diff --git a/include/configs/tegra-common.h b/include/configs/tegra-common.h
+#ifndef CONFIG_ARM64 #ifndef CONFIG_SPL_BUILD #define CONFIG_USE_ARCH_MEMCPY #endif +#endif
We don't need SPL, but that stanza used to enable ARCH_MEMCPY *except* for SPL. I would expect we still want ARCH_MEMCPY on ARM64, where presumably ifndef CONFIG_SPL_BUILD will always be true?
First we need arch memcpy/memset for aarch64 copied over (and maybe update the 32bit one and get everyone using them).
