Public bug reported:
---Problem Description---
opal-prd fix for Ubuntu 18.04
In some corner cases where opal-prd fails to access/read flash device
(/dev/mtd0) we see opal-prd consuming 100% cpu. This mostly happens during boot
time where opal-prd daemon tries to start even before mtd driver loaded. Its
not easy to reproduce. It happens randomly.
---uname output---
Ubuntu 18.04
Machine Type = OpenPower System
Userspace tool common name: opal-prd
Below upstream patch will fix this issue.

opal-prd: Insert powernv_flash module
Explictly load powernv_flash module on BMC based system so that we are sure
that flash device is created before starting opal-prd daemon.
