Following earlycon patch for exynos soc was merged in Linux 4.0-rc1.
- commit-id: b94ba0328d3b36ff95f5074c0e9b44f90dc56bb5 (serial: samsung: Add support for early console)
Almost Exynos SoC use the same UART IP of Exynos4210.

If you mean that "earlycon=exynos4210" naming will be changed to "earlycon=exynos",
we have to modify the drivers/tty/serial/samsung.c.

Thanks,
