I am however having a more difficult time getting the linux kernel=20
(linuxppc=5F2=5F4=5Fdevel from Denx) to work with PCF8563.  I get error=

It works fine on the PM520...

Thanks for your hints.  I tried configuring the kernel for the pm520 board
(make PM520=5Fconfig) and then the RTC stuff works on my board.  Obviously I
had something misconfigured that resulted in the strange behaviour of i2c.

Is this correct?
No, it is actually incorrect and this is something that I need to fix.
My board (NS4) has a DP83847 PHY on the FEC.  I modified fec.c to avoid
kernel panic, but I do not have the PHY handling 100% correct yet.
Ethernet communications are working though, at least when connected to=20
a Cisco Catalyst 2950 with autonegotiation it establishes 100 Mbps Full=20
Duplex.
When connected to an old HP 10Mbps hub linux reports as above, 100 MBps=20
Half Duplex,
but the communications do work despite wrong reported speed.

Any suggestions for reference code for DP83847 with MPC5200 ?

Many thanks,
