From 786842b62f81f20d14894925e8c225328ee8144b Mon Sep 17 00:00:00 2001 From: Stewart Smith Date: Wed, 9 Dec 2015 17:18:18 +1100 Subject: [PATCH] powerpc/powernv: panic() on OPAL < V3 The OpenPower Abstraction Layer firmware went through a couple of iterations in the lab before being released. What we now know as OPAL advertises itself as OPALv3. OPALv2 and OPALv1 never made it outside the lab, and the possibility of anyone at all ever building a mainline kernel today and expecting it to boot on such hardware is zero.
