Don't know of any support, but I would point out that if they are similar, 
then adding a configuration option to the existing cs8900a driver is the 
best route.

If you mean how to do the ethernet support at all, look at one of the 
other ethernet drivers for the cs8900a, for example the edb7xxx ethernet 
driver. Essentially there are two packages: the cs8900a driver itself, and 
the edb7xxx driver which supplies platform-specific information the 
cs8900a driver needs. Both packages are then mentioned in the ecos.db 
target for the edb7xxx.
