Exactly.  Most drivers are divided into a generic portion (the part
that understands the actual device and the work the driver needs to
accomplish) plus a target/platform specific portion (which describes
how the device is configured, addresses, interrupts, and such).  
Depending on the driver, the platform specific portion may come in
the form of an include file or a driver wrapper.  These details are
described by the CDL for the driver.

Look at other platforms which use the RHINE ethernet driver to see
what needs to be done.
