I don't see a problem here, the patch should not change the behavior at all.

The whole entry now looks like:

        config DEBUG_S3C_UART0
                depends on PLAT_SAMSUNG || ARCH_S5PV210 || ARCH_EXYNOS
                select DEBUG_EXYNOS_UART if ARCH_EXYNOS
                select DEBUG_S3C24XX_UART if ARCH_S3C24XX
                select DEBUG_S3C64XX_UART if ARCH_S3C64XX
                select DEBUG_S5PV210_UART if ARCH_S5PV210
                bool "Use Samsung S3C UART 0 for low-level debug"

so this will work as before with any of ARCH_EXYNOS, ARCH_S3C24XX,
ARCH_S3C64XX and ARCH_S5PV210.

What am I missing?
