security/vboot/sync_ec: Add timestamps
Add 4 new timestamps to the EC software sync flow: 1) Beginning of EC software sync 2) EC finished calculating Vboot hash 3) EC is no longer requesting power limiting 4) End of EC software sync BUG=none BRANCH=none TEST=verified timestamps show up in cbmem log Change-Id: I6e5703c146b5ec27d01700fdb39cb3d2092ea8a8 Signed-off-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/36209 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Julius Werner <jwerner@chromium.org>
