There were two undefined MBP types that are now defined. These include NFC status and some interesting timing data. ME: Wake Event to ME Reset: 6 ms ME: ME Reset to Platform Reset: 7 ms ME: Platform Reset to CPU Reset: 51 ms Change-Id: I67bf1f303f3c32497041e64c40eb9ccb6a63d88a Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/49756 Reviewed-on: http://review.coreboot.org/4152 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.
