for the enumerated PHYs. As the original commit comment states, I was
getting these messages:

prom_parse: Bad cell count for /qe@e0100000/mdio@2120/ethernet-phy@00
prom_parse: Bad cell count for /qe@e0100000/mdio@2120/ethernet-phy@01

Well, I would say it's a bug to try to translate addresses accross such
a boundary. Thus the PHY enumeration code is bogus.

I also wonder why it hangs on the powerbook... Rutger, I would expect to
see that complaint warning with the reverted patch, what does it say ?

My Wallstreet (also based on Grackle) doesn't have the problem. Also can
you send me a tarball of /proc/device-tree ?

I don't have any of those machines, but it seems that older kernels
running on the Lombard emitted:

device-tree: Duplicate name in /cpus/PowerPC,750@0, renamed to "l2-cache#1"

That's a different matter.

messages*.  Experimenting with adding two chosen nodes (due to a prior
thread on this list**) results in a hung kernel on the 8360 also, so
perhaps they're related (and the kernel's tolerance to duplicate
entries has changed, which explains where I had seen the chosen node
being renamed).

but yeah, size-cells should be allowed to be 0 (even address-cells) and
it may be the case that the Lombard needs some fixup code.
