Subject: [PATCH V3 9/9] powerpc: Enable support of ibm,dynamic-memory-v2
Date: Fri, 01 Dec 2017 10:48:03 -0600	[thread overview]
Message-ID: <151214687950.64022.15779582389677722807.stgit@ltcalpine2-lp14.aus.stglabs.ibm.com> (raw)
In-Reply-To: <151214667699.64022.17601877129884655591.stgit@ltcalpine2-lp14.aus.stglabs.ibm.com>

Add required bits to the architecture vector to enable support
of the ibm,dynamic-memory-v2 device tree property.
