FSP memory init hang on Apollolake MRB

I am trying to boot Coreboot on Apollolake (Gordon Peak) MRB board. I have been able to build and flash the binary and it starts to boot but hangs in FSP memory initialization.

As per the documents I have, the board has an LPDDR4 memory module. So I dumped the MRC settings from the boot loader that was already running on the board and configured UPD to match it but did not have any success. Now I have run out of options. Can anyone help here?

Below is the log from serial console:
