And the ebony dts also has the a bus type of "ibm,opb" as well.

We should really get a common name for these. I don't remember
what the discussions were, but it seems we came up with different
results for Axon and ppc4xx, which is very bad.

Yes, using common types would be a very good idea. There's no published
DTS for Axon so we have no idea what has been previously defined.

Using type "ibm,opb" rather than just "opb" makes sense to me,
but I don't know if we already have shipping systems that use
"opb" here.

I would prefer "ibm,xxx" as well if it's possible.

There is probably a similar problem with the nodes for "plb4",
"plb5" and "ebc", as well as the "compatible" property of the
serial port, which, as you noted earlier is "ns16550" on 
ebony and "ns16750" on axon, although it is exactly the same
macro.

Right, ebony is currently using "ibm,plb".  We haven't defined an EBC
node yet for 4xx.
