Subject[PATCH] serial: earlycon requires console support
Date
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. This patch adds the 'select'
to make serial-samsung behave like the other drivers.
