Domen,

Do it in a Forth script, or in nvramrc (after probe-all). Don't clutter
Linux with more fixups. The Efika PHY isn't going to change to something
else and it's a bog standard no-frills MII PHY anyway.

I think it is a distinction that the OF docs forgot to make, that the
client interface is *all those Forth words* and not just the 6 or 7
distinct, special callable functions like claim (they exist because of
the simple fact that claiming memory shouldn't involve claiming memory
and such other paradoxes) and call-method. Call-method is a perfectly
valid way of doing things.

But, I'd really recommend you please think of a different way.. if you
want to spec out a device tree entry for it I'll update my script which
I am probably going to stick as an 'official' Genesi support file in
the next week.

If you insist on using prom_init and fixups, yaboot has the best
examples of call-method and interpret, both readable and fairly
easily available.

I am struggling with this part on Efika.
I would like to add this to the device tree from
fixup_device_tree_efika() (arch/powerpc/kernel/prom_init.c).

AFAICS client-services doesn't offer anything like new-device,
so I guess "interpret" or "call-method" will have to be used.

I have read some docs, but I'm still wandering in the dark.
Can I please get an example?
Pretty please with a cherry on top?
