For ARM32 architecture, CONFIG_DEBUG_LL is available for early low-level debugging (and actually UniPhier 32bit SoCs use it), but ARM64 architecture does not support it. Instead, CONFIG_DEBUG_UART is available as an architecture-independent debug facility. This commit supports it on all the UniPhier SoCs (including the new ARMv8 SoCs), which is very useful for new SoC bringups. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
