    sandybridge: Make build possible without descriptor.bin
    
    On newer Intel systems, the flash ROM is shared between the host
    processor (BIOS), it's 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.
    
    This patch adds 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 won't be written over (nor any other section that hasn't been
    included by coreboot). A patch to write selected sections of a flash ROM
    with IFD has been sent to the flashrom mailing list [1].
