So out it goes as well.

The PORT_S3C2400 definition in include/linux/serial_core.h is left there
to prevent a reuse of the same number for another port type.

The Samsung S3C24XX range of ARM9 System-on-Chip CPUs are supported
by the 's3c2410' architecture of ARM Linux. Currently the S3C2410,
S3C2412, S3C2413, S3C2416 S3C2440, S3C2442, S3C2443 and S3C2450 devices
S3C2412, S3C2413, S3C2416, S3C2440, S3C2442, S3C2443 and S3C2450 devices
are supported.
Support for the S3C2400 and S3C24A0 series are in progress.
Support for the S3C2400 and S3C24A0 series was never completed and the
corresponding code has been removed after a while. If someone wishes to
revive this effort, partial support can be retrieved from earlier Linux
versions.
The S3C2416 and S3C2450 devices are very similar and S3C2450 support is
included under the arch/arm/mach-s3c2416 directory. Note, whilst core
