Make coreboot use the offset parameter in cbfstool create
On Sandybridge and Ivybridge systems the firmware image has to store a lot more than just coreboot, including: - a firmware descriptor - Intel Management Engine firmware - MRC cache information This option allows to limit the size of the CBFS portion in the firmware image.
