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.
