From 357d56151976a78d90dc3dfac01777de0ef05212 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 19 May 2015 22:26:04 +0200 Subject: [PATCH] serial: samsung: only use earlycon for console A configuration that enables earlycon but not the core console code causes a link error: drivers/built-in.o: In function `setup_earlycon': drivers/tty/serial/earlycon.c:70: undefined reference to `uart_parse_earlycon' That error can be triggered by the newly added samsung earlycon support, which is missing a 'select' statement. As suggested by Peter Hurley, solves the problem by moving the 'select SERIAL_EARLYCON' statement to the samsung console driver option, as it is done by all other console drivers.
