This patch creates individual files for each programmer's lifecycle tests. Common functions that are reusable for all tests are gathered in lifecycle.c. Each individual file needs to include lifecycle.h BUG=b:237606255 TEST=ninja test Change-Id: If2307699dcbb3a085b91a2dcd41156e6fd07f812 Signed-off-by: Anastasia Klimchuk <aklm@chromium.org> Reviewed-on: https://review.coreboot.org/c/flashrom/+/65543 Reviewed-by: Peter Marheine <pmarheine@chromium.org> Reviewed-by: Felix Singer <felixsinger@posteo.net> Reviewed-by: Edward O'Callaghan <quasisec@chromium.org> Reviewed-by: Thomas Heijligen <src@posteo.de> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
