[coreboot] Help on setting clock speed in coreboot

Hi Team

I have a customized board based on Intel valley island design. Reference design uses Intel Baytrail processor E3825, while my design is using E3845.

I am customizing coreboot for this E3845, but getting just garbage on coreboot, so not able to debug where it is stuck.

When I add memory test as secondary payload, I cd see some operations happening on console but not able to decode it.

Tried with all possible baud rates, but no success. USB and display also not enumerating.

Can you please give some clue? Is it due to different core speed for E3835(1.33GHZ) vs E3845(1.91GHz).

Where is the option to change this in coreboot?

Appreciate your support.

Regards
Mayuri
