On newer Intel systems, like Intel Lynx Point, the flash ROM is shared
between the host processor (BIOS), its Management Engine (ME) and an
integrated Ethernet controller (GbE). The layout of the flash ROM (and
other information) is kept in the so called Intel Firmware Descriptor
(IFD). If we only want to build coreboot to update the BIOS section,
all we need is the flash layout.
So add the option to specify the flash layout in the mainboard’s
Kconfig, and thus, to build without the real IFD. However, with such a
build, one has to make sure that the IFD section on the flash ROM will
not be written over (nor any other section that has not been included
by coreboot). A patch to write selected sections of a flash ROM with
IFD has been sent to the flashrom mailing list [2].
The same was done in commit a15cd66b [1] (sandybridge: Make build
possible without descriptor.bin) for Intel Sandy Bridge (BD82x6x).
