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.

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.

With timC being direct function of timB's 6 LSBs it's critical to match timC and timB. Some tests increments the value of timB by a small value, which might cause the 6bit value to overflow, if it's close to 0x3F. Increment the value by a small offset if it's likely to overflow, to make sure it won't overflow while running tests and bricks the system due to a non matching timC. In comparission to the first attempt, only 4 out of 128 timB values are considered bad. Needs test on real hardware ! Fixes a "edge write discovery failed" on my test system.

Issue observed: The PCIe Root port shows up in GNU/Linux but no PCIe device is being detected. Test system: * Gigabyte GA-B75M-D3H (Intel Pentium CPU G2130) * Lenovo T530 (Intel Core i5-3320M CPU) Problem description: The PEG Root port link training on Ivy Bridge needs to be manually started. Problem solution: The bits are set in early_init to meet PCIe reset timeout of 100msec. The bits should be set in PCI device enable function, but this causes the PCI enumeration to not detect the card, as it's still booting. Adding a fixed delay of 100msec resolves this problem, but this would increase boot time. Read the PCI base revision mask to make sure it's any IvyBridge CPU. Don't run the code on MRC path as it has its own PEG initilization code. Tested with: * Nvidia NVS 5400M (PCIe2) * ATI Radeon HD4780 (PCIe2) * Nvidia GeForce 8600 GT (PCIe1) Untested: * PCIe3 devices Final test results: The PEG device shows up under GNU/Linux and can be used without issues.

2016-02-10Kconfig: Move defaults for CBFS_SIZEMartin Roth
We want the question for CBFS size to be next to the rom size in the mainboard directory, but that doesn't seem to work for how people want to set the defaults. Instead of having the list of exceptions to the size, just set the defaults at the end of kconfig. - Move the defaults for chipsets not setting HAVE_INTEL_FIRMWARE into the chipset Kconfigs (gm45, nehalem, sandybridge, x4x) - Override the default for HAVE_INTEL_FIRMWARE on skylake. - Move the HAVE_INTEL_FIRMWARE default setting into the firmware Kconfig file - Move the location of the default CBFS_SIZE=ROM_SIZE to the end of the top level kconfig file, while leaving the question where it is. Test=rebuild Kconfig files before and after the change, verify that they are how they were intended to be. Note: the Skylake boards actually changed value, because they were picking up the 0x100000 from HAVE_INTEL_FIRMWARE instead of the 0x200000 desired. This was due to the SOC_INTEL_SKYLAKE being after the HAVE_INTEL_FIRMWARE default. Affected boards were: Google chell, glados, & lars and Intel kunimitsu.

This reverts commit 0e06f5bd70b45fd330d8dfb1dc77cce043caf841. It breaks gm45 and also does some magic without being asked too. It disables bridge devices permanently if no device was found on the se- condary bus. In a simple notebook world this might be ok, but it breaks hot-plugging and late detection (if a secondary bus device comes up too slow for the firmware to detect and the OS has to enumerate it).

2016-02-04nb/intel/sandybridge/raminit: Fix two dimms per channelPatrick Rudolph
Issue observed: The system boots with 4G in channel 0 and 4G in channel 1. The system doesn't boot with any combination of 4G + 1G in channel 0 and 4G in channel 1. In both cases DIMM1 failed, while DIMM0 showed no issues. Problem description: The CLK to CMD/CTL was off by a half clock cycle. The find the issue I X-Y plotted timC vs timB for every lane on the failing rank. You can see an offset by 32 units for timB, that is not present on other ranks. It turns out that the XOVER CMD/XOVER CTL enable bit for DIMM1 was missing in program_timings(), which caused the clock offset. Problem solution: Add two functions to calculate XOVER CMD and XOVER CTL and use both to set XOVER in program_timings() and dram_xover(). Final testing result: The system boots with 4G + 1G in channel 0 and 4G in channel 1.
