2024-04-13sandybridge,haswell,broadwell: Use DIV_ROUND_CLOSEST macroAngel Pons
Integer division in C truncates toward zero. When the dividend and the divisor are positive, one can add half of the divisor to the dividend to round the division result towards the closest integer. We already have a macro in commonlib to do just that, so put it to good use. Tested with BUILD_TIMELESS=1, coreboot images for the Asus P8Z77-V LX2 and the Asrock B85M Pro4 do not change.

2022-08-14broadwell: Decouple LPDDR3 DQ/DQS maps from `pei_data`Angel Pons
Introduce the `BROADWELL_LPDDR3` Kconfig option along with some wrapper code to allow mainboards using LPDDR3 DRAM to supply the DQ/DQS maps to chipset code without having to use `pei_data`. The only mainboard using LPDDR3 is Google Samus.

2022-08-14soc/intel/broadwell: Consolidate SPD handlingAngel Pons
Mainboards do not need to know about `pei_data` to tell northbridge code where to find the SPD data. As done on Haswell, add the `mb_get_spd_map` function and the `struct spd_info` type to retrieve SPD information from mainboard code without having to use `pei_data` in said mainboard code. Unlike Haswell MRC, Broadwell MRC uses all positions of the `spd_data` array, not just the first. The placeholder SPD address for memory-down seems to be different as well. Adapt the existing code to handle these variations. Once complete, the abstraction layer for both MRC binaries will have the same API.

2022-08-14broadwell: Compute channel disable masks at runtimeAngel Pons
Introduce the `SPD_MEMORY_DOWN` macro to indicate that a slot is used with memory-down. This enables computing the channel disable masks as the bits for slots where the SPD address is zero. To preserve current behavior, zero the SPD addresses for memory-down slots afterwards.

2022-03-08timestamps: Rename timestamps to make names more consistentJakub Czapiga
This patch aims to make timestamps more consistent in naming, to follow one pattern. Until now there were many naming patterns: - TS_START_*/TS_END_* - TS_BEFORE_*/TS_AFTER_* - TS_*_START/TS_*_END This change also aims to indicate, that these timestamps can be used to create time-ranges, e.g. from TS_BOOTBLOCK_START to TS_BOOTBLOCK_END.

2020-11-13mrc_cache: Move code for triggering memory training into mrc_cacheShelley Chen
Currently the decision of whether or not to use mrc_cache in recovery mode is made within the individual platforms' drivers (ie: fsp2.0, fsp1.1, etc.). As this is not platform specific, but uses common vboot infrastructure, the code can be unified and moved into mrc_cache. The conditions are as follows: 1. If HAS_RECOVERY_MRC_CACHE, use mrc_cache data (unless retrain switch is true) 2. If !HAS_RECOVERY_MRC_CACHE && VBOOT_STARTS_IN_BOOTBLOCK, this means that memory training will occur after verified boot, meaning that mrc_cache will be filled with data from executing RW code. So in this case, we never want to use the training data in the mrc_cache for recovery mode. 3. If !HAS_RECOVERY_MRC_CACHE && VBOOT_STARTS_IN_ROMSTAGE, this means that memory training happens before verfied boot, meaning that the mrc_cache data is generated by RO code, so it is safe to use for a recovery boot. 4. Any platform that does not use vboot should be unaffected. Additionally, we have removed the MRC_CLEAR_NORMAL_CACHE_ON_RECOVERY_RETRAIN config because the mrc_cache driver takes care of invalidating the mrc_cache data for normal mode. If the platform: 1. !HAS_RECOVERY_MRC_CACHE, always invalidate mrc_cache data 2. HAS_RECOVERY_MRC_CACHE, only invalidate if retrain switch is set BUG=b:150502246 BRANCH=None TEST=1. run dut-control power_state:rec_force_mrc twice on lazor ensure that memory retraining happens both times run dut-control power_state:rec twice on lazor ensure that memory retraining happens only first time 2. remove HAS_RECOVERY_MRC_CACHE from lazor Kconfig boot twice to ensure caching of memory training occurred on each boot.
