Anyway, my reason for this message is to suggest a runtime diagnostic 
message somewhere if address 0 is used - this could have saved me a lot of 
work! If someone can suggest the right place to add this I can prepare a 
patch.

Address 0 can be made special or not, but there is no programmatic way
to tell without scanning the MDIO bus for devices, so I don't think a
warning is going to help at all to warn about that. There are also tons
of cases where the address is just treated like any other address, which
is typical with MDIO connected Ethernet switches where PHY@0 is just the
switch's port 0 built-in PHY for instance.

Thanks for the quick reply; I'll forget that idea.

Regarding the actual problem with the 0 address on this board, I
have been told that someone at APM is going to look into it.  Fingers
crossed that it's fixable somewhere in a driver.  I'll update the list
if necessary.


Cheers,  Phil.
