2016-12-07PCI ops: MMCONF_SUPPORT_DEFAULT is requiredKyösti Mälkki
Doing PCI config operations via MMIO window by default is a requirement, if supported by the platform. This means chipset or CPU code must enable MMCONF operations early in bootblock already, or before platform-specific romstage entry. Platforms are allowed to have NO_MMCONF_SUPPORT only in the case it is actually not implemented in the silicon.

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).

2016-11-22spi: Clean up SPI flash driver interfaceFurquan Shaikh
RW flag was added to spi_slave structure to get around a requirement on some AMD flash controllers that need to group together all spi volatile operations (write/erase). This rw flag is not a property or attribute of the SPI slave or controller. Thus, instead of saving it in spi_slave structure, clean up the SPI flash driver interface. This allows chipsets/mainboards (that require volatile operations to be grouped) to indicate beginning and end of such grouped operations. New user APIs are added to allow users to perform probe, read, write, erase, volatile group begin and end operations. Callbacks defined in spi_flash structure are expected to be used only by the SPI flash driver. Any chipset that requires grouping of volatile operations can select the newly added Kconfig option SPI_FLASH_HAS_VOLATILE_GROUP and define callbacks for chipset_volatile_group_{begin,end}. spi_claim_bus/spi_release_bus calls have been removed from the SPI flash chip drivers which end up calling do_spi_flash_cmd since it already has required calls for claiming and releasing SPI bus before performing a read/write operation.

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 I expect the differences to be an update (i.e. the set- tings we did on the Sandy Bridge path were just outdated).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.

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.

2016-09-27i945/gma.c: Generate fake VBTArthur Heymans
This generates a fake VBT for the Intel i945 graphic device. i945 supports both the mobile chipset 945gm (calistoga) and the desktop chipset 945gc (lakeport), which is why a VBT with a different id string needs to be created for each target. The VBT id string is obtained from the vbios blob in the following way: "strings vbios.bin | grep VBT".

2016-09-19gm45/gma.c: use screen on vga connector if connectedArthur Heymans
The intel x4x and gm45 have very similar integrated graphic devices. Currently the x4x native graphic init enables VGA, while gm45 can output on LVDS. This patch reuses the x4x graphic initialisation code to enable output on VGA in gm45 in a way that the behavior is similar to vbios: If no VGA display is connected the internal LVDS screen is used. If an external screen is detected on the VGA port it will be used instead.
