Serial driver of S5PC100 is the same as S3C6400, so S5PC100 shares the serial
driver with S3C6400. Uart driver is copied from plat-s3c64xx to plat-s5pc1xx,
as I do not use plat-s3c64xx directory.

S5PC100's the physical IO space starts at 0xe000"0000. To maximize space for
vmalloc, the virtual IO space starts at 0xf400"0000 as same as other samsung
CPUs(s3c24xx and s3c64xx) do.
