That's not a bug.  The check is meant to indicate whether the weak 
board_eth_init() function has been overridden, not whether there was an 
error.  I have a clarification patch that hasn't been submitted yet.

No, it is a bug. Board_eth_init() calls pci_eth_init() (include/netdev.h)
and if ethernet is soc, CONFIG_PCI is not defined, pci_eth_init() returns 0.
This patch allows cpu_eth_init() to be called.

> Sorry, still not a bug.  The behavior you've described should be handled
internally to your specific board_eth_init() function.  If no PCI devices
are found either because none are present or because you didn't specify the
CONFIG_PCI option, you can call cpu_eth_init().

Fixes: Board_eth_init() calls pci_eth_init() (include/netdev.h) and if
ethernet is soc, CONFIG_PCI is not defined, pci_eth_init() returns 0.
This patch allows cpu_eth_init() to be called.

Do you have this patch in your queue?

No, I don't.  This patch is wrong, and I believe I already responded 
about it.  The code does need a subtle clean-up, but I haven't quite 
found the time to do it.  Hopefully in the next couple of days I'll get 
to it.

Thanks. I asked because after your reply there was a "But..." from Teh
Kok How which AFAICT remained unreplied, so I wa snot sure.

I see that now.  Thought I'd responded, but I guess not.  Anyway, the 
right fix for the problem Teh Kok How is (was?) seeing is to have a 
smarter board_eth_init() function.
