2016-09-02drivers/intel/fsp2_0: Make FSP Headers Consumable out of BoxBrandon Breitenstein
The following patch is based off of the UEFI 2.6 patch. The FSP header files are temporarily staying in soc/intel/apollolake and FspUpd.h has been relocated since the other headers expect it to be in the root of an includable directory. Any struct defines were removed since they are defined in the headers and no longer need to be explicity declared as struct with the UEFI 2.6 includes.

2016-07-19drivers/intel/fsp2_0: Split reset handling logicAndrey Petrov
FSP 2.0 spec only defines 2 reset request (COLD, WARM) exit codes. The rest 6 codes are platform-specific and may vary. Modify helper function so that only basic resets are handled and let SoC deal with the rest.

2016-07-19soc/intel/apollolake: Implement reset_prepare()Andrey Petrov
At first boot CSE spends long time preparing media for use. As result it may not be able to deal with a CPU reset. Add reset_prepare() callback that polls CSE readiness. BUG=chrome-os-partner:55055 TEST=build with release version of fsp, reboot, observe polling for CSE, then proper reboot happening Change-Id: I639ef900b97132f1a7f269bb864d70009df9fdfe Signed-off-by: Andrey Petrov <andrey.petrov@intel.com> Reviewed-on: https://review.coreboot.org/15721 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>
2016-06-24soc/intel/apollolake: Add utility functions for global resetAndrey Petrov
Apollolake defines Global Reset where Host, TXE and PMC are reset. During boot we may need to trigger a global reset as part of platform initialization (or for error handling). Add functions to trigger global reset, enable/disable it and lock global reset bit.

2016-06-24Revert "intel/apollolake: Use custom reset calls"Andrey Petrov
Looks like we need to do real cold reset in some FSP flows, so reverting this. This reverts commit 6f762171de4b8514fddd430052cbf24524e09e5d.

2016-06-12intel/apollolake: Use custom reset callsFurquan Shaikh
Due to USB LDO issue in current steppings, cold reboot needs to be temporarily disabled. Thus, hard_reset call should be the same as soft_reset. Once future steppings are available INTEL_COMMON_RESET can be enabled again.
