This is OK short term, can you see if turning on DM in SPL is easy for these platforms instead? Thanks!

The exynos5 platforms use DM in U-Boot and do not use DM in SPL. The serial driver, serial_s5p.c, is DM-only. This is OK for U-Boot, but in SPL, this will fail with the following compile error: drivers/built-in.o: In function `get_current': ...u-boot/drivers/serial/serial.c:387: undefined reference to `default_serial_console' This warning happens because common/console.c is compiled into U-Boot SPL if CONFIG_SPL_SERIAL_SUPPORT . The common/console.c invokes serial_*() functions and since exynos5 does not use DM in SPL, these functions come from drivers/serial/serial.c . The serial_*() locate default serial port by calling default_serial_console(), but because the serial_s5p.c is DM-only, it does no longer define default_serial_console(). Thus the error.
