From: "Aneesh Kumar K.V" <aneesh.ku...@linux.vnet.ibm.com>
The patch adds CPU PVR definition for POWER9 and enables QEMU to launch
guests/linux-user in TCG mode.
Signed-off-by: Aneesh Kumar K.V <aneesh.ku...@linux.vnet.ibm.com>
[ Added POWER9 alias, POWER9 SPAPR core and dropped MMU defines ]
Signed-off-by: Nikunj A Dadhania <nik...@linux.vnet.ibm.com>
[dwg: Dropped sPAPR core type again for now]
