Yes, since the "ARCH=" parameter from the compiler helps to route it to
the right directory, arch/arm or arch/arm64, and you cannot compile both
in a single image. Same case for other SoCs, e.g., tegra (ARCH_TEGRA),
exynos (ARCH_EXYNOS), and etc.
The benefit of sharing the same arch flag is that the device driver that
exists in iProc family of SoCs (both arm32 and arm64) can be guarded or
