soc/intel/apollolake: Implement stage cache to improve resume time
This patch enables stage cache to save ~40ms during S3 resume. It saves ramstage in the stage cache and restores it on resume so that ramstage does not have to reinitialize during the resume flow. Stage cache functionality is added to postcar stage since ramstage is called from postcar. BUG=chrome-os-partner:56941 BRANCH=none TEST=built for Reef and tested ramstage being cached Change-Id: I1551fd0faca536bd8c8656f0a8ec7f900aae1f72 Signed-off-by: Brandon Breitenstein <brandon.breitenstein@intel.com> Reviewed-on: https://review.coreboot.org/16833 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net>
