For EEH on PowerNV platform, the overall architecture is different from that on pSeries platform. In order to support multiple I/O chips in future, we split EEH to 3 layers for PowerNV platform: EEH core, platform layer, I/O layer. It would give EEH implementation on PowerNV platform much more flexibility in future. The patch adds the EEH backend for P7IOC.
