This patch adds UART serial port support for S5P6440 CPU. Most of the
serial support of Samsung's 6400 CPU is reused for 6440 CPU.

I can't see this being used anywhere. Another thing is that it looks
like a re-defined on S3C2410_LCON_CS8 (it seems S3C2410_LCON is a mis-type
f S3C2410_ULCON). Please get rid of this change unless it breaks the build.

This is a problem, you've got two configurations with the same target
file. Forget the fact S5PC100 sneaked in a third, I will remove this and
elide the configuration now i've seen it. It should not have been merged
in the first place, must have missed it.
Please re-use CONFIG_SERIAL_S3C6400, building the same file from different
configurations provides the possibility of not only confusing the build
system, but with ending up with the same object as both a module and a
builtin.
