From: Shyam Sundar <ssundar@xxxxxxxxxxx>
* Firmware Initialization with SCM enabled based on NVRAM setting and
firmware support (About Firmware).
* Enable PUREX and add support for fabric performance impact
notification(FPIN) handling.
* Allocate a default purex item for each vha, to handle memory
allocation failures in ISR.
