The cpu model to pvr value mappings are
POWER7 -> '0x003f0200'
POWER7_v2.1 -> '0x003f0201'
POWER7_v2.3 -> '0x003f0203'
POWER7+_v2.1 -> '0x004a0201'
POWER8_v1.0 -> '0x004b0100'

> Currently, PPC CPU driver doesn't support to parse guest data.
> It can't pass CPU parameters to Qemu command line.
>
> This patchset is to implement .guestData to support to parse guest
> CPU configuration and .update to support host-model and
host-passthrough.
>
> The guest CPU configuration is as the following:
> <cpu match='exact'>
> <model>POWER7_v2.3</model>
> <vendor>IBM</vendor>
> </cpu>
>
> v2 -> v1:
> * Remove features functions calling for non-x86 platform (Doug
Goldstein)
> * Improve update code.
> * Merge update code with guestData.
>
> Li Zhang (3):
> Remove CPU features check for non-x86 platform.
> cpu: Implement guestData and update for PPC
> cpu: Add cpu test cases for PPC CPU driver.
