2017-03-10device/dram/ddr2: Add common ddr2 spd decoderPatrick Rudolph
Decode DDR2 SPD similar to DDR3 SPD decoder to ease readability, reduce code complexity and reduce size of maintainable code. Rename dimm_is_registered to spd_dimm_is_registered_ddr3 to avoid compilation errors.

2017-03-08binaryPI platforms: Drop any ACPI S3 supportKyösti Mälkki
No board with binaryPI currently supports HAVE_ACPI_RESUME. For platforms with PSP the approach is also very different from what we previously had here. Furthermore, s3_resume.[ch] files under cpu/amd/pi do not distinguish between NonVolatile and Volatile buffers of S3 storage. This means the Volatile buffer that is maintained and available in CBMEM is unnecessarily copied to SPI flash. This has been fixed on open-source AGESA directory, so development of S3 suspend support with binaryPI is better continued with that. Unfortunately there are further complications and indications that open-source AGESA may have always had a low-memory corruption issue. This has to be investigated separately before restoring or claiming S3 is supported on binaryPI.

This reverts commit fec8872c9dee4411ba1a89fc8ec833a700b476c6. The commit introduced a regression which is causing MC4 failures when 8 RDIMMs are populated in a configuration with a single CPU package. Using just 4 RDIMMs, the failure does not occur. After reverting the commit, I tested configurations with 1 CPU (8x8=64GB) and 2 CPU packages (16x8=128GB) using an Opteron 6276. The MC4 failures did not occur anymore.

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.

The selection of the SSC reference frequency for LVDS was based on a completely unrelated clock. The `ssc_freq` flag should be set when the SSC reference runs at a different frequency than the general display reference clock (DREF). For most platforms, there is no choice, i.e. for i945 and gm45 the SSC reference always differs from the display reference clock (i945: 66Mhz SSC vs. 48MHz DREF; gm45: 100MHz SSC vs. 96Mhz DREF), for Nehalem and newer, it's the same frequency for SSC/non-SSC (120MHz). The only, currently supported platform with a choice seems to be Pineview, where the alternative is 100MHz vs. the default 96MHz.

2017-01-10nb/intel/945gc: Hardcode the integrated graphic frequenciesArthur Heymans
The code to set the igd frequencies is written with the mobile version of the 945 chipset in mind and seems to cause cause strange igd related problems on the desktop versions. Some possible problems are: * on 800MHz fsb CPUs the igd sometimes has artifacts on the screen; * on 800MHz fsb CPU memtest results vary a lot; * since a commit 45e11aa0a5 "Add/Combine Broadwell Chromebooks using variant board scheme" that does not affect this northbridge, the display shows garbage as soon as Linux (4.8) modesets the display. A fix is to hardcode the core display and render clocks to their maximum, potentially also improving graphical performance. Vendor bios on all boards in coreboot with this northbridge have the same value in this PCI config address. TESTED on P5GC-MX (display works fine again in Linux) and user reports of it making GA-945GCM-S2L run more stable.
