2024-10-01soc/intel: Correct return type of fsp_get_pch_reset_status()Subrata Banik
The `fsp_get_pch_reset_status()` function returns a FSP reset status code. This change corrects its return type from `uint32_t` to `efi_return_status_t` to ensure consistency with the FSP API and prevent potential issues caused by type mismatch. This correction is necessary for compatibility with both 32-bit and 64-bit FSP interfaces. The change also updates all callers of this function in the Meteor Lake and Panther Lake SoCs to use the correct return type. Includes `fsp/api.h` to provide the `efi_return_status_t` definition. BUG=b:347669091 TEST=Verified global reset functionality on google/rex0 (32-bit) and google/rex64 (64-bit) platforms.

2023-05-02soc/intel/common: Introduce API to get the FSP Reset StatusSubrata Banik
This patch creates a function to read the FSP API Reset Status. This function relies on the FSP Scheduled Reset HOB which holds the reset type (warm/cold/shutdown) information along with any platform specific reset need (like global reset). Ideally FSP API should be able to return the status (both success and error code) upon exiting the FSP API but unfortunately there are some scenarios in ADL/RPL FSP where MultiPhaseSiInit API is unable to return any ERROR status. Hence, this function provides an additional hook to read the FSP reset status by reading the dedicated HOB without relying on the FSP API exit status code. Additionally, create FSP_MULTIPHASE_SI_INIT_RETURN_BROKEN config option to handle broken FSP API return status issue. Any SoC platform that selects the `FSP_MULTIPHASE_SI_INIT_RETURN_BROKEN` config will call into this newly added API to get the FSP return status from MultiPhaseSiInit. BUG=b:278665768 TEST=Able to select FSP_MULTIPHASE_SI_INIT_RETURN_BROKEN for ADL/RPL SoC code and call into this API to know the return status from MultiPhaseSiInit FSP API.

Make direct call to global_reset() from cse_lite.c 7. Drop CONFIG_HAVE_CF9_RESET_PREPARE Kconfig from APL SoC due to common reset (soc/intel/common/reset.c) code migration 8. Remove unused function send_global_reset() from SKL me.c due to common reset code migration 9.

2018-10-22intel: Use CF9 reset (part 2)Patrick Rudolph
Make use of the common CF9 reset in SOC_INTEL_COMMON_RESET. Also implement board_reset() as a "full reset" (aka. cold reset) as that is what was used here for hard_reset(). Drop soc_reset_prepare() thereby, as it was only used for APL. Also, move the global-reset logic. We leave some comments to remind us that a system_reset() should be enough, where a full_reset() is called now (to retain current behaviour) and looks suspicious. Note, as no global_reset() is implemented for Denverton-NS, we halt there now instead of issuing a non-global reset. This seems safer; a non-global reset might result in a reset loop.
