This replaces magic values by macros and adds some comments to improve readability. Adds a convenient function to fetch the test address of a rank. Also fixes the temporary memory map by changing a write to MCHBAR 0x100 to 0x110, since this is what vendor does.

2018-04-17nb/intel/x4x: Refactor setting default dll settingsArthur Heymans
This patch pushes these large default delay tables to a different file to reduce cluttering up the actual raminit source. While doing so it also uses more but smaller arrays and also adds the respective default delays for DDR3 which are not yet used in this patch. This patch add a function to set the read DQS delays instead of just programming magic values. (This will prove useful for DQS read training) To prepare for adding trainings on the delay values it stores these default delays in the sysinfo struct to program those. Later when trainings are implemented those trained values will be used instead of these safe default values, via using the cached sysinfo in 'mrc' cache.

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.

This moves disabling the watchdog reboot to the northbridge code like i945 (even though it technically is southbridge stuff).

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.

It rewrites the results of receive enable stored in the upper nvram region, to avoid running receive enable again. Some debug info is also printed about the self-refresh registers. (Not enforcing a reset here, since 0 does not necessarily mean it's not in self-refresh).

2017-02-17nb/intel/x4x: Fix raminit on reset pathArthur Heymans
Previously the raminit failed on hot reset and to work around this issue it unconditionally did a cold reset. This has the following issues: * it's slow; * when the OS issues a hot reset some disk drives expect their 5V power supply to remain on, which gets cut off by a cold reset, causing data corruption. To fix this some steps in raminit must be ommited on the reset path. This includes receive enable calibration. To achieve this it stores receive enable results in RTC nvram for them to be rewritten on the resume path. Note: The same thing needs to be done on the S3 resume path. Calling a hot reset after raminit "outb(0x6, 0cf9)" works.

2017-01-22nb/x4x/raminit: Fix programming dram timingsArthur Heymans
The results were obtained by comparing the MCHBAR registers of vendor bios with coreboot at the same dram timings. This fixes 2 issues: * 1333MHz fsb CPUs were limited to 667MHz ddr2 speeds, because with 800MHz raminit failed; * 1067MHz fsb CPUs did not boot when second dimm slot was populated. TESTED on ga-g41m-es2l on 800, 1067 and 1333MHz CPUs with DDR2 667 and 800MHz dimms.

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).
