IPC timed out after boot on Yorp #277
Description
This regression is caused by the ABI change, since the ABI is changed in firmware side, but the according kernel PR /pull/260 is missing in cros-sof-v4.14-rebase branch.

@keqiaozhang thanks. I will update the cros branch after the ABI changes have been validated

@ranj063 Please hold on backporting PR /pull/260 to the topic/cros-4.14-rebase branch. Please backport after release for this week is done.
Firmware glk-004-drop-stable branch plan to introduce ABI update for IPC refinement AFTER the release this week. Only SOF master branch has the ABI update atm.

@mengdonglin there is no plan to provide a different driver so firmware HAS to update. The ABI change was reviewed and no one from the firmware team chimed in, so silence means consent...

Closing this issue because now kernel branch topic/cros-sof-v4.14-rebase is aligned with FW branch glk-004-drop-stable. And FW branch glk-004-drop-stable will not include any ABI change if not necessary for a hot fix.
So ABI update like thesofproject/sof@9af90ce will not be included in glk-004-drop-stable. Thus no need to backport PR /pull/260 to the topic/cros-4.14-rebase branch.
