 ok this may just be an error in the documentation.  apparently the
Exynos5 doesn't have built-in ethernet.  if however it has a similar
General-Purpose Memory Bus (similar to TI's HPI) just like the S3C6410
does, then chances are you could put things like DM9000s directly
attached to it.  DM9000 Ethernet PHYs have 2 modes - MII and also an
8-bit parallel data/address bus mode.  i'm sure that there are
10/100/1000 Ethernet PHYs out there with 16-bit interfaces.

 all rather odd, though.  anyway, the arndaleboard uses USB-ETH rather
than GPMB PHYs.
