The file name in the comment doesn't match. I normally recommend not putting
it in the comment at all so you don't need to change it when moving or
copying the file.

A comment along the lines of "s5pv310 platform with device tree enabled" is
more helpful to the reader anyway.

There is very little here that is really platform specific, right?

Is this going to increase? If not, it might be good to read out the
data (S5P_VA_CHIPID, 24000000, smdkv310_uartcfgs) from the device tree
as well before passing them down. No need to do it right away, but it
would be good to know the direction in which we're heading.

Maybe add a comment like /* TODO: read these from the device tree */
or similar.
