2020-09-21soc/intel: Refactor do_global_reset() functionSubrata Banik
List of changes: 1. Rename do_global_reset() to force_global_reset() 2. Make force_global_reset() function static 3. Implement force_global_reset() into common/reset.c to avoid dedicated SoC implementation 4. Remove redundant force_global_reset() implementation from dedicated SoC 5. 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. Delete heci.c from APL SoC as unused Signed-off-by: Subrata Banik <subrata.banik@intel.com> Change-Id: I1c5dc8d5606ef28ffaed4a64d90f470ae1ffc2a6 Reviewed-on: https://review.coreboot.org/c/coreboot/+/45541 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>

2020-03-18soc: Remove copyright noticesPatrick Georgi
They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

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.

2017-06-13Consolidate reset API, add generic reset_prepare mechanismJulius Werner
There are many good reasons why we may want to run some sort of generic callback before we're executing a reset. Unfortunateley, that is really hard right now: code that wants to reset simply calls the hard_reset() function (or one of its ill-differentiated cousins) which is directly implemented by a myriad of different mainboards, northbridges, SoCs, etc. More recent x86 SoCs have tried to solve the problem in their own little corner of soc/intel/common, but it's really something that would benefit all of coreboot. This patch expands the concept onto all boards: hard_reset() and friends get implemented in a generic location where they can run hooks before calling the platform-specific implementation that is now called do_hard_reset(). The existing Intel reset_prepare() gets generalized as soc_reset_prepare() (and other hooks for arch, mainboard, etc. can now easily be added later if necessary). We will also use this central point to ensure all platforms flush their cache before reset, which is generally useful for all cases where we're trying to persist information in RAM across reboots (like the new persistent CBMEM console does). Also remove cpu_reset() completely since it's not used anywhere and doesn't seem very useful compared to the others.

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.

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.
