PS1, Line 13: TEST=Build francka and do EC reset to check the SSD boots to OS successfully
> How much was the boot time improvement?

The DUT does not have enough time to initialize SSD if the power sequence is configured in ramstage.
The image.bin cannot boot from internal disk(SSD).
Therefore, the settings are moved in romstage to get more time for SSD initialization.
