help
If you don't have an Intel Firmware Descriptor (ifd.bin) for your
board, you can select this option and coreboot will build without it.
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.

help
The Intel processor in the selected system requires a special firmware
for an integrated controller called Management Engine (ME). 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_MBP_CLEAR_LATE
bool "Defer wait for ME MBP Cleared"

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"

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.
