From c37a6684818d41051c54f814863429536aa972be Mon Sep 17 00:00:00 2001 From: Patrick Delaunay Date: Tue, 11 Oct 2022 16:44:26 +0200 Subject: stm32mp: fix compilation issue with DEBUG_UART Fix the compilation issue when CONFIG_DEBUG_UART is activated drivers/serial/serial_stm32.o: in function `debug_uart_init': drivers/serial/serial_stm32.c:291: undefined reference to \ `board_debug_uart_init' The board_debug_uart_init is needed for SPL boot, called in cpu.c::mach_cpu_init(); it is defined in board/st/stm32mp1/spl.c. But with the removal #ifdefs patch, the function debug_uart_init() is always compiled even if not present in the final U-Boot image. This patch adds a file to provided this function when DEBUG_UART and SPL are activated.
