I don't quite understand.  The uart driver will support a
variety of SMC/SCC combinations.

We have discussed before that we are not doing "scc" or "smc"
drivers, but rather "uart", "ethernet", "usb", whatever function
driver.  It doesn't make sense to have an 'scc' driver because
there are so many configuration combinations and you logically
connect to the kernel with a function (i.e. network interface)
not a device type.

Well, in the case of multiple SCC ethernets, I have provided my old
patch to probably a half a dozen people, all who promised to
bring it up to date and apply some suggested improvements.  None
of them have provided anything up to date in return, so I guess
I'll have to take time to do that, too :-)  The 8260 FCC driver
supports any combination of FCC Ethernet devices.


Thanks.
