For the Harcuvar CRB there is no such configuration.

This conf. is available to other mainboards (e.g. Intel "Little Plains"
mainboard:
menu "Chipset"->"Intel Firmware"->"Add Intel descriptor.bin file"->"Add
Intel
ME/TXE firmware"->"Path to management engine firmware").

Maybe for the Harcuvar CRB the Intel ME FW is installed in the second
SPI flash, therefore there is no need to add the ME blob in the coreboot
build? I´m not sure about this, some board maintainer can confirm
this?

Do we have any documentation regarding the coreboot port for Harcuvar?

Thanks,
Sumo
