[Qemu-devel] [PATCH v0] spapr: Restore support for older PowerPC CPU cores

[Bharata B Rao <bharata@linux.vnet.ibm.com>]

Introduction of core based CPU hotplug for PowerPC sPAPR didn't
add support for 970 and POWER5+ based core types. Add support for
the same.

TODO:
- There are few other variants of 970, like 970fx etc for which I have not
  added core types since I am not sure if they fall under sPAPR category.
- Is it time to add core type for POWER8NVL yet ?
