Re: [PATCH 1/4] powerpc/powernv: Add OPAL check token call

Michael Neuling [off-list ref] writes:

Currently there is no way to generically check if an OPAL call exists or not
from the host kernel.

This adds an OPAL call opal_check_token() which tells you if the given token is
present in OPAL or not.

(although should we be checking if the call returns OPAL_PARAMETER?
The opal call will return that if booting on firmware without
OPAL_CHECK_TOKEN.. which granted, is pretty old firmware that I don't
*think* we had leave the lab... or at least not to too many places)
