This pull requests consists of features to the iBFT driver. Specifically:

 - support v1.03 of the spec. The spec in question is available at:
   ftp://ftp.software.ibm.com/systems/support/bladecenter/iscsi_boot_firmware_table_v1.03.pdf
 - separate the iBFT parsing from the SysFS interface.


What is iBFT?
The iBFT is an equivalent to the Boot Flag, except that its geared
towards iSCSI and hence requires much more information (such as
the IP of target, passwords, which device to login, etc). iBFT
is a data structure populated by the BIOS or the NIC to contain this
so that the OS can read it and login to the iSCSI and present
the boot device to the initrd for mounting / FS.

Thanks,

	Konrad
