t132: Add timestamp collection support in t132
Add a region TIMESTAMP to store all the timestamps starting from bootblock to end of romstage. At the end of romstage take all the timestamps in TIMESTAMP region and put it into cbmem BUG=chrome-os-partner:32973 BRANCH=None TEST=Compiles successfully and cbmem -t prints all timestamps Original-Change-Id: I856564de80589bede660ca6bc1275193f8a2fa4b Original-Signed-off-by: Furquan Shaikh <furquan@google.com> Original-Reviewed-on: https://chromium-review.googlesource.com/223110 Original-Reviewed-by: Aaron Durbin <adurbin@chromium.org> Original-Tested-by: Furquan Shaikh <furquan@chromium.org> Original-Commit-Queue: Furquan Shaikh <furquan@chromium.org> (cherry picked from commit b8ccf5731df9ca149a2a0661362e7745515bfe5e) Signed-off-by: Marc Jones <marc.jones@se-eng.com> Change-Id: I266e46ed691ebe5f0a20ed28b89e6e74399487a1 Reviewed-on: http://review.coreboot.org/10736 Reviewed-by: Aaron Durbin <adurbin@chromium.org> Tested-by: build bot (Jenkins)
