2016-11-20intel sandy/ivy: Improve DIMM replacement detectionKyösti Mälkki
When MRC cache is available, first read only the SPD unique identifier bytes required to detect possible DIMM replacement. As this is 11 vs 256 bytes with slow SMBus operations, we save about 70ms for every installed DIMM on normal boot path. In the DIMM replacement case this adds some 10ms per installed DIMM as some SPD gets read twice, but we are on slow RAM training boot path anyways.

2016-11-20intel sandy/ivy: Skip SPD loading on S3 resume pathKyösti Mälkki
For S3 resume path SPD is only used for DIMM replacement detection. As this detection already fails in the case of removal/insertion of same DIMM, we can rely on cbmem_recovery() failure alone to force system reset in case someone accidentally does DIMM replacements while system is suspend-to-ram stage. Skipping DIMM replacement detection allows skipping slow SPD loading, thus reducing S3 resume path time by 80ms for every installed DIMM.

These settings should be always made by the firmware, no matter if we set up graphics or not. It looks like Linux doesn't even know these registers. The values are taken from the PRMs for Sandy Bridge and Ivy Bridge [1, 2]. They match the settings that were done in the native graphics path for Ivy Bridge. I expect the differences to be an update (i.e. the set- tings we did on the Sandy Bridge path were just outdated). Also, these settings affect the PCH and not the CPU which are independent from each other.

This reuses linux code (at least 4.1) to compute the graphic clock divisors for LVDS displays on the gm45 northbridge. The divisors m1, m2, n, p1, p2 need to be such that "BASE_FREQUECY * (5 * (m1 + 2) + (m2 + 2)) / (n + 2) / (p1 * p2)" is as close as possible to the target_frequency.

The datasheets on gm45: "Mobile Intel® 4 Series Express Chipset Family" mention the possibility of having 352M ram preallocated for the integrated graphic device. This only worked fine if the amount of ram in the system was 3GB or less. When 4G or more is installed, memory is remapped to create a 1GB large pci mmio hole which is not enough and creates conflicts when 352M vram is used. This patch increases the pci mmio hole size on Lenovo x200 to allow 352M vram to work. TEST: build and flash on target with 4GB ram or more, use nvramtool to set gfx_uma_size to 352M and reboot.

2016-09-30i945/gma.c: use linux code to calculate divisorsArthur Heymans
The code to compute n, m1, m2, p1 divisors is not correct in coreboot and on some targets hits a working mode at lower refresh rate, which is why display is working on some targets. The divisors must be such "refclk * (5 * (m1 + 2) + (m2 + 2))/ (n + 2) / (p1 * p2)" is as close as possible to the target frequency (which is defined by the resolution and refresh rate). This patch also fixes the reference frequency. This patch reuses linux (4.1) code from drivers/gpu/drm/i915/intel_display.c to correctly compute divisors. The result is that some previously not working displays, like many displays found on the Lenovo T60 might work now. Some examples of T60 displays that were known to not work (in payload): Samsung LTN141XA-L01 (14.1" 1024x768) LG-Philips LP150X09 (15.1" 1024x768) IDtech N150U3-L01 (15.1" 1600x1200) IDtech IAQX10N (15.1" 2048x1536) Samsung LTN154X3-L0A (15.4" 1280x800) LG-Philips LP150E06-A5K4 (15.1" 1400x1050) Tested on T60 with 1024x786.

Previously the ME PCI interface (HECI) was being reported as present in the DMAR ACPI table even when ME firmware was missing or the PCI device was hidden and HECI would be unresponsive. Now we check via the PCI config space itself to verify if the HECI is present or not. Note that this test could fail if ME firmware is present but HECI is disabled in devicetree, because it would not advertise that the HECI exists even though there is a running ME. Perhaps this behaviour is desirable because in this case you won't see the HECI in the lspci tree anyway.

According to "G45: Volume 3: Display Register Intel ® 965G Express Chipset Family and Intel ® G35 Express Chipset Graphics Controller" some registries are set incorrectly in gm45/gma.c. Some values are changed after comparing them with the values the i915 linux kernel (3.13 was used) module sets while modesetting. The values were obtained using 'intel_reg' from intel-gpu-tools, during a normal boot and with 'nomodeset' as a kernel argument. Some registers that don't exist on gm45 are set in gma.c, which is probably the result of copying code from a more recent intel northbridge. The result is that that gm45 laptops with wxga displays still work as before. gm45 laptops with wxga+ or higher resolution now just work, where previously a black screen was shown. TEST: build with native graphic init and flash on a gm45 target, like lenovo x200.

2016-08-31i945: Enable changing VRAM sizeArthur Heymans
On i945 the vram size is the default 8mb. It is also possible to set it 1mb or 0mb hardcoding the GGC register in early_init.c The intel documentation on i945, "Mobile Intel® 945 Express Chipset Family datasheet june 2008" only documents those three options. They are set using 3 bits. The documententation also makes mention of 4mb, 16mb, 32mb, 48mb, 64mb but not how to set it. The other non documented (straight forward) bit combinations allow to change the VRAM size to those other states. What this patch does is: - add those undocumented registers with their respective vram size to the i945 NB code; - make this a cmos option on targets that have this northbridge. TEST: build, flash to target, set cmos as desired and boot linux. On Debian it can be found using "dmesg | grep stolen". NOTE: dmesg message about reserved vram are quite different depending on linux version Change-Id: Ia71367ae3efb51bd64affd728407b8386e74594f Signed-off-by: Arthur Heymans <arthur@aheymans.xyz> Reviewed-on: https://review.coreboot.org/14819 Tested-by: build bot (Jenkins) Reviewed-by: Martin Roth <martinroth@google.com>

TESTED most options on ga-g41m-es2l with 2G dimm in one slot and 2x2G. 352M also works in contrast with gm45 where it is known to cause issues with certain ram combinations.

2016-07-27nb/intel/x4x: Fix CAS latency detection and max memory detectionDamien Zammit
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.
