vboot: add mocked secdata
This patch allows a board without a secdata storage (typically TPM) to pass the verification stage if recovery path is taken. It's useful for bringup when the actual board is not ready. BUG=none BRANCH=none TEST=booted the kernel from a usb stick on a cygnus reference board Change-Id: I5ab97d1198057d102a1708338d71c606fe106c75 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Original-Commit-Id: 5d45acee31fd5b7bfe7444f12e3622bae49fc329 Original-Signed-off-by: Daisuke Nojiri <dnojiri@chromium.org> Original-Reviewed-on: https://chrome-internal-review.googlesource.com/212418 Original-Reviewed-by: Daisuke Nojiri <dnojiri@google.com> Original-Commit-Queue: Daisuke Nojiri <dnojiri@google.com> Original-Tested-by: Daisuke Nojiri <dnojiri@google.com> Original-Change-Id: Iddd9af19a2b6428704254af0c17b642e7a976fb8 Original-Reviewed-on: https://chromium-review.googlesource.com/265046 Reviewed-on: http://review.coreboot.org/9919 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
