debug_uart_init() is called from spl_board_init(), which is only compiled for SPL. For U-boot proper, _debug_uart_init() is unreachable, so dropped by the dead code elimination. Now that 64-bit SoCs of this SoC family no longer support SPL, debug-uart-ld20.c is never compiled. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
