Does this look okay Hari ?
During MPIPL (aka fadump), after a kernel crash, the kernel does
opal_cec_reboot2 opal call, signifying an abnormal termination.
When OPAL recieves this opal call, it further triggers SBE S0 interrupt,
to trigger a MPIPL boot.
Currently S0 interrupt is unimplemented in QEMU.
