This patch adds support for Boot from SAN over iSCSI offload. The iSCSI boot information in the NVRAM is populated under /sys/firmware/iscsi_bootX/ using qed NVM-image reading API and further exported to open-iscsi to perform iSCSI login enabling boot over offload iSCSI interface in a Boot from SAN environment.
