Thank you once again for your help and support.
Managed to build the coreboot 16MB image with FSP, ifwi and descriptor.bin and flashed it on the board. When power-on board, I see Red LED (DS3B1) is ON that seems to be some error. User guide only provide description of 4 LEDs (DS6B1, DS2C1, DS6B2, D5L1) so I assume red led is indicating some error condition.
Currently: DS6B1 : Green ON DS6B2 : Green ON DS2C1 : OFF DS3B1 : RED ON
No Output on serial console or HDMI.
Red light is never a good sign. Do you have a way to know if PLTRST# has been de-asserted?
Another thing is that when you stitch with FIT you need to turn off boot guard completely. I suspect you have it on and that makes CSE to check signatures. Please check that in Platform protection -> Bootguard configuration it is set to "bootguard profile 0 - legacy". Then try restitching fit image and rebuilding coreboot again.
