From e3d5d3ac5bbbddddf830a918e59c13f7a8d9ef6c Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sat, 29 Jun 2019 02:38:05 +0900 Subject: ARM: uniphier: remove unused init code for CONFIG_DEBUG_UART 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.
