Coreboot fails to write MRC cache to this particular chip, therefore resume is not working after suspend to RAM (instead, the machine boots as if it was a cold boot).

However, after internal flashing with flashrom and subsequent reboot coreboot is able to write MRC cache and resume is working.
However, if we then completely turn off the power for a few minutes and then boot and try to suspend-resume again, coreboot fails to write MRC cache again and resume is not working.
