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.
Fixes: 699cc4dfd140 ("tty: serial: imx: add imx earlycon driver")

If you have enabled the earlycon on the Freescale IMX
CPU you can make it the earlycon by answering Y to this option.
