This patch writen by Peter Jones and Mike Christie expands on the
iBFT firmware driver to 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

Linux kernel has support for the iBFT 1.0 spec and this update to 1.03
adds three more things:
 - There is now a ACPI table either called 'iBFT' or 'IBFT' that should
   be parsed.
 - If running with UEFI, only look at the ACPI table.
 - If not found within ACPI tables, fall back to the old mechanism of scanning
   memory for the signature.

It has been tested with gPXE and also a real hardware (Mike, did I get that right?)
