You've still got CONFIG_ARMV8 in places that should be CONFIG_ARM64
I am hesitate to use CONFIG_ARM64 instead of CONFIG _ARMV8. I am not sure whether all the CONFIG_ARMV8 could be replaced with CONFIG_ARM64 or CONFIG_ARMV8 and CONFIG_ARMV64 are both needed. I will take this into account in the next.
If it inherently relates to being 64-bit (including ABI issues), use CONFIG_ARM64. If it's something that is new in ARMv8 but isn't specifically due to 64-bitness (e.g. cache stuff, if it's different from ARMv7), and could reasonably be different in a 64-bit ARMv9, then use CONFIG_ARMV8.
