4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Stewart Smith stewart@linux.vnet.ibm.com
commit 786842b62f81f20d14894925e8c225328ee8144b upstream.
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.
