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 HEAP_SIZE hex default 0x80000 config IED_REGION_SIZE hex default 0x400000 config IFD_BIN_PATH string "Path to intel firmware descriptor" depends on !BUILD_WITH_FAKE_IFD default "3rdparty/blobs/mainboard/$(MAINBOARDDIR)/descriptor.bin" config IFD_BIOS_SECTION depends on BUILD_WITH_FAKE_IFD string default "" config IFD_ME_SECTION depends on BUILD_WITH_FAKE_IFD string default "" config IFD_PLATFORM_SECTION depends on BUILD_WITH_FAKE_IFD string default "" config ME_BIN_PATH string "Path to management engine firmware" depends on HAVE_ME_BIN default "3rdparty/blobs/mainboard/$(MAINBOARDDIR)/me.bin" config MMCONF_BASE_ADDRESS hex "MMIO Base Address" default 0xe0000000 config MONOTONIC_TIMER_MSR def_bool y select HAVE_MONOTONIC_TIMER help Provide a monotonic timer using the 24MHz MSR counter. config PRE_GRAPHICS_DELAY int "Graphics initialization delay in ms" default 0 help On some systems, coreboot boots so fast that connected monitors (mostly TVs) won't be able to wake up fast enough to talk to the VBIOS.
