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).
Oh, that's missing? OK, it makes sense to disable it. However, the
commit description probably shouldn't imply this is related to having
SPL or not, but rather that ARM64 doesn't support ARCH_MEMCPY yet?
