the following patch was just integrated into master: commit 6e3289372c598e3e0702f44e52c04d689172b156 Author: Aaron Durbin adurbin@chromium.org Date: Wed Nov 6 12:04:50 2013 -0600
baytrail: add support for S3 resume
Previously the only path through memory init and coreboot was hardcoding S5. Therefore all S3 paths would not be taken. Allow for S3 resume to work by enabling the proper control paths in romstage.
BUG=chrome-os-partner:22867 BRANCH=None TEST=While in kernel 'echo mem > /sys/power/state'. Board went into S3. Power button press resumed back into kernel.
