From 24c796926e2f88b383a76ddc871a7cdd62484f3a Mon Sep 17 00:00:00 2001 From: Yang Yingliang Date: Sat, 19 Sep 2020 14:32:40 +0800 Subject: [PATCH] tty: serial: imx: fix link error with CONFIG_SERIAL_CORE_CONSOLE=n aarch64-linux-gnu-ld: drivers/tty/serial/imx_earlycon.o: in function `imx_uart_console_early_write': imx_earlycon.c:(.text+0x84): undefined reference to `uart_console_write' The driver uses the uart_console_write(), but SERIAL_CORE_CONSOLE is not selected, so uart_console_write is not defined, then we get the error. Fix this by selecting SERIAL_CORE_CONSOLE.
