2020-08-24mrc_cache: Add mrc_cache fetch functions to support non-x86 platformsShelley Chen
Create two new functions to fetch mrc_cache data (replacing mrc_cache_get_current): - mrc_cache_load_current: fetches the mrc_cache data and drops it into the given buffer. This is useful for ARM platforms where the mmap operation is very expensive. - mrc_cache_mmap_leak: fetch the mrc_cache data and puts it into a given buffer. This is useful for platforms where the mmap operation is a no-op (like x86 platforms). As the name mentions, we are not freeing the memory that we allocated with the mmap, so it is the caller's responsibility to do so. Additionally, we are replacing mrc_cache_latest with mrc_cache_get_latest_slot_info, which does not check the validity of the data when retrieving the current mrc_cache slot. This allows the caller some flexibility in deciding where they want the mrc_cache data stored (either in an mmaped region or at a given address). BUG=b:150502246 BRANCH=None TEST=Testing on a nami (x86) device: reboot from ec console. Make sure memory training happens. reboot from ec console. Make sure that we don't do training again.

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.

2018-04-17nb/intel/x4x: Use SPI flash to cache raminit resultsArthur Heymans
Stores information obtained from decoding dimms and receive enable results for future use. Depreciates using rtc nvram to store receive enable settings. A notable change is that receive enable results are always reused, not just on a resume from S3. This requires cbmem to be initialized a bit earlier, right after the raminit finished to be able to add the sysinfo struct to cbmem which gets cached to the SPI flash in ramstage. TESTED on Intel DG43GT with W25Q128.V. With 4 ddr2 dimms time in raminit goes from 133,857ms (using i2c block read to fetch SPD) to 21,071ms for cached results.

2017-12-16nb/x4x/raminit: Rewrite SPD decode and timing selectionArthur Heymans
This is mostly written from scratch and uses common spd ddr2 decode functions. This improves the following: * This fixes incorrect CAS/Freq detection on DDR2; * Fixes tRFC computation; tRFC == 78 is a valid timing which is excluded and 0 ends up being used; (TESTED) * Timings selection does not use loops; * Removes ddr3 spd decode and is re-added in follow-up patches using common ddr3 spd functions; * Raminit would bail out if a dimm was unsupported, now in some cases it just marks the dimm slot as empty; * It dramatically reduces stack usage since it does not allocate 4 times 256 bytes to store full SPDs, amongs other unused things that were stored in sysinfo; * Reports when no dimms are present; * Uses i2c block read to read SPD which is about 5 times faster than bytewise read, with a fallback to smbus mode in case of failure, which does seem to happen when the system is forcefully powered off.

2017-05-04nb/intel/x4x/raminit: Change reset type on incomplete raminit resetArthur Heymans
The checkreset() function checks if raminit previously succeeded (pmcon2 bit7 == 0). If this is not the case it will issue a hot reset (writing 0x6 to 0xcf9). On the next attempt to boot the system BOOT_PATH_RESET path will be taken. This boot path can only successfully initialize memory if the system was reset from a state where raminit succeeded, which is not the case here. This can be fixed by issuing a cold reset instead of a hot reset.

Fix-up for 696abfc nb/intel/x4x: Fix and deflate `dimm_config` in raminit It didn't fix the channel-number shifting issue as intended. The channel index is either 0 or 1. DIMMs are counted from 0 to 3 where 0..1 covers channel 0, and 2..3 covers channel 1. Since we have two DIMMs per channel, we have to multiply the channel index by 2 (or shift it left by 1) to get the index of the first DIMM in the channel. Finally, to get the offset of a DIMM in the channel we take its index modulo 2 (again, the number of DIMMs per channel).

Now hardcode maximum memory frequency capability to 800MHz, as all chipsets in x4x family support PC2-6400 according to the datasheet. CAS latency detection also relies on this, and has been cleaned up. Ram initialization does not work with FSB 1333MHz / DDR2 800MHz combination, so disable this combination for now, and reduce to 667MHz instead. Still don't know why this is the case, but FSB1333/667 works. These changes should now allow existing configurations to continue working, while providing support for previously unworking configurations, due to previous buggy CAS latency detection code.
