arm64: kconfig: allow CPU_BIG_ENDIAN to be selected
This patch wires up CONFIG_CPU_BIG_ENDIAN for the AArch64 kernel configuration. Selecting this option builds a big-endian kernel which can boot into a big-endian userspace. Signed-off-by: Will Deacon <will.deacon@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
