[coreboot] Changing DRAM Frequency

[Tapasya Patki]

Hi,

I'm working on a research project for dynamic voltage/frequency scaling for
DRAM.

I am aware that coreboot initializes DRAM and sets its frequency
(cache-as-ram) during boot. I would like to know if it is possible to change
the DRAM frequency by following the same initialization sequence without
rebooting the system (along with preserving the application's memory
context).

Thanks,
Tapasya Patki
