Subject: [PATCH V2 1/5] powerpc/dynmemv2: Check arch.vec earlier during boot for memory features
Date: Mon, 17 Apr 2017 10:03:42 -0500	[thread overview]
Message-ID: <149244139775.49112.6141577889382304374.stgit@powerkvm6.aus.stglabs.ibm.com> (raw)
In-Reply-To: <149244134630.49112.5423447491302011316.stgit@powerkvm6.aus.stglabs.ibm.com>

architecture.vec5 features: The boot-time memory management needs to
know the form of the "ibm,dynamic-memory-v2" property early during
scanning of the flattened device tree.  This patch moves execution of
the function pseries_probe_fw_features() early enough to be before
the scanning of the memory properties in the device tree to allow
recognition of the supported properties.
