Re: [PATCH] powerpc/powernv: Remove powernv RTAS support

Michael Ellerman [off-list ref] writes:

The powernv code has some conditional support for running on bare metal
machines that have no OPAL firmware, but provide RTAS.

No released machines ever supported that, and even in the lab it was
just a transitional hack in the days when OPAL was still being
developed.

So remove the code.

So when we select CONFIG_PPC_PSERIES, we end up selecting
CONFIG_PPC_RTAS. What is the expected behaviour there for powernv ? Can
we use RTAS call from powernv code if rtas node is present in device
tree ? Or do we want to make sure powernv always use OPAL call ?

For example, right now we will use rtas_node get-term-char and
put-term-char even with this patch applied.
