BUG=chrome-os-partner:28772 BRANCH=nyan TEST=booted on Big, ran "mosys eventlog list" and saw "System boot" event logged with boot count == 0 Original-Change-Id: I729e28feb94546acf6173e7b67990f5b29d02fc7 Original-Signed-off-by: David Hendricks <dhendrix@chromium.org> Original-Reviewed-on: https://chromium-review.googlesource.com/204525 Original-Reviewed-by: Julius Werner <jwerner@chromium.org> (cherry picked from commit 2598dc63ddc0d76bcdf9814cadd4c75653fd9832) Signed-off-by: Marc Jones <marc.jones@se-eng.com> Change-Id: Ieb4e2e36870e97d9c5f88f0190291863a65a6351 Reviewed-on: http://review.coreboot.org/8142 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
