Please adopt new-style names with dashes, i.e. "allwinner-emac". Peter
C.'s comment wrt TYPE_* still applies though.

Since you're using DEVICE() twice, you should consider using a local
variable like you did for sysbusdev below. It's a one-time
initialization though, so not mandatory.

"phy-addr"?

error_report() always without trailing \n.

Bad example. ;) Fixes welcome.
