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].
