[Qemu-devel] [PATCH v1 2/3] sPAPR: Implement sPAPRPHBClass::format_errinjct_cmd

[Gavin Shan <gwshan@linux.vnet.ibm.com>]

The patch implements sPAPRPHBClass::format_errinjct_cmd to do the
address translation (BUID+PE number to IOMMU group ID) and then
come up with the formatted string for PCI error injection.
