2016-10-07soc/intel/apollolake: Disable HECI2 device reset on S3 resumeAndrey Petrov
Converged Security Engine (CSE) has a secure variable storage feature. However, this storage is expected to be reset during S3 resume flow. Since coreboot does not use secure storage feature, disable HECI2 reset request. This saves appr. 130ms of resume time. BUG=chrome-os-partner:56941 BRANCH=none TEST=powerd_dbus_suspend; resume; check time with cbmem -t. Note FspMemoryInit time is not significantly different from normal boot time case.

2016-10-07soc/intel/apollolake: Implement stage cache to improve resume timeBrandon Breitenstein
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.

2016-03-23soc/intel/apollolake: utilize postcar phase/stageAaron Durbin
The current Apollolake flow has its code executing out of cache-as-ram for the pre-DRAM stages. This is different from past platforms where they were just executing-in-place against the memory-mapped SPI flash boot media. The implication is that when cache-as-ram needs to be torn down one needs to be executing out of DRAM since the act of cache-as-ram going away means the code disappears out from under the processor. Therefore load and use the postcar infrastructure to bootstrap this process for tearing down cache-as-ram and subsequently loading ramstage.
