FSP1_0 places romstage ram stack at fixed location of
RAMTOP in low memory before returning to coreboot proper.
There is no possibility of making a complete backup of
RAMBASE..RAMTOP region and currently such backup is not
even attempted.
As a conclusion, S3 resume would always cause OS memory
corruption.
