the following patch was just integrated into master:
commit 5a596f7a8fb66d12c2888d8bb91ea883c2fceea0

Add constants for fast path resume copying
cache as ram does not usually cache the ram before it is up. Hence,
if romstage.c backs up resume memory, the involved memcpy is always
uncached. This makes resume very slow.
On Sandybridge we copy the memory later, after enabling caching, and
that allows us to resume in as little as 250ms.
