Dear Tor Krill,
In message 1277716302.2221.37.camel@tor-desktop you wrote:
- For the boards using single port will also need to configure PHY address
for other port, which is meaningless, unnecessary and confusing.
Sure you had to put something there to be on the safe side. But is that really that confusing, the SOC really have two ports, them being used or not?
It is indeed confusing and should be avoided if one has to configurwe hardware ports that are not actually present or used on a specific board.
If needed, provide sane defaults internally in the code.
But keep in mind that U-Boot requires that only used peripherals should be initialized - we should not initisalize any unused ports.
Best regards,
Wolfgang Denk

Let's say the docs present a simplified view of reality... :-)
