Though, the resulting coreboot.rom will not contain all parts required to get coreboot running on your board. You can however write only the BIOS section to your board's flash ROM and keep the other sections untouched. Unfortunately the current version of flashrom doesn't support this yet. But there is a patch pending [1]. WARNING: Never write a complete coreboot.rom to your flash ROM if it was built with a fake IFD. It just won't work.

The ME firmware might be provided in coreboot's 3rdparty/blobs repository. If not and if you don't have the firmware elsewhere, you can still build coreboot without it. In this case however, you'll have to make sure that you don't overwrite your ME firmware on your flash ROM. config ME_BIN_PATH string "Path to management engine firmware" depends on HAVE_ME_BIN default "3rdparty/blobs/mainboard/$(MAINBOARDDIR)/me.bin" config ME_MBP_CLEAR_LATE bool "Defer wait for ME MBP Cleared" default y help If you set this option to y, the Management Engine driver will defer waiting for the MBP Cleared indicator until the finalize step. This can speed up boot time if the ME takes a long time to indicate this status. config FINALIZE_USB_ROUTE_XHCI bool "Route all ports to XHCI controller in finalize step" default y help If you set this option to y, the USB ports will be routed to the XHCI controller during the finalize SMM callback. config LOCK_MANAGEMENT_ENGINE bool "Lock Management Engine section" default n help The Intel Management Engine supports preventing write accesses from the host to the Management Engine section in the firmware descriptor. If the ME section is locked, it can only be overwritten with an external SPI flash programmer. You will want this if you want to increase security of your ROM image once you are sure that the ME firmware is no longer going to change. If unsure, say N. endif
