BIOS development for Intel RPL -SUD5-1DPC 4L microATX CRB FAB1

[leenaarora18]

We built coreboot for Intel Alder Lake RVP, but got this warning:

WARNING
coreboot has been built without an Intel Firmware Descriptor (IFD). Never write a complete coreboot.rom without an IFD to your
board's flash chip! Use flashrom's IFD or layout parameters to flash only the BIOS region.

We have successfully generated the coreboot.rom for the alder lake

Now How can I include the Intel Firmware Descriptor (IFD) in my build?

Need help on this. Can anyone suggest what to do?
