commit 0b63b0c428bc2ed4e9d4fc00429e0cbc7f6e5a31 Author: Stefan Reinauer reinauer@chromium.org Date: Wed Aug 15 16:28:48 2012 -0700
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.
