No, it has nothing to do with that. It is only skeleton code that someday may perform a patch. The drivers are not yet updated to handle it. The microcode patches either work correctly or not at all, there is no in between. I have never used an SCC Ethernet on the FADS, but there must be control register bits or other 8xx general purpose I/O pins that are required to be set correctly for the Ethernet PHY to operate correctly. You have to also make sure all of the SCC clock and I/O pins are properly configured for the hardware design. I can guarantee some of this may not be correct for the 823 FADS, as all boards seem to use something different. The 8xx SCC Ethernet driver will only run on half duplex mode. There is no auto sensing like is provided on (some) FEC 10/100 Ethernet PHYs. The SCC (and FEC) has to be configured differently for half or full duplex operation. -- Dan ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
