[coreboot] Extracting MRC training data

[Antony AbeePrakash X V]

Hi All,

We are developing coreboot for Apollo lake custom board.  MRC training data is enabled in FSP using Binary configuration tool.

We are facing the following observations:

1.  After flashing the first boot takes 10 sec to boot.
  2.  For next cold boot the boot time takes 6 sec and remains same.

So we dumped the flashed coreboot image and re-flashed the dumped coreboot image to the chip.

1.  After flash the first boot takes 6 sec to boot.
  2.  For next cold boot also the same 6 sec is observed.

Could you please explain on the above observations ?

Can we extract the MRC training data and add it to the coreboot image ? If yes, could you please share the steps to be done ?

Thanks & Regards,
Antony
