Coreboot

Coreboot, formerly known as LinuxBIOS, provides a modern BIOS/firmware implementation for many modern processors and chipsets.

mb/hp: Add new port compaq_8200_elite_sff
Patrick Rudolph: Add new port based on autoport. The board uses a NPCD378 SuperIO, that is full of custom hardware. The 8MiB flash SOIC-8 can be accessed after cutting of a part of the DIMM slot holder.

AMD: Remove some leftover includes
Kyösti Mälkki

mb/gigabyte/ga-h61m-s2pv: Add new mainboard
Angel Pons: Tested with GRUB 2.02 as a payload, booting Arch Linux with latest kernel.

nb/intel/x4x/raminit: Add DDR3 enhanced mode and power settings
Arthur Heymans

nb/intel/x4x/raminit: Add DDR3 specific dra/drb settings
Arthur Heymans: When programming the final dram attribute and dram boundary settings, on DDR3 dram one also needs to enable ZQCAL in the CxREFRCTRL (DRAM Refresh Control) register as documented in "Intel ® 4 Series Chipset Family" documentation.

nb/intel/x4x: Implement write leveling
Arthur Heymans: DDR3 adapted a fly-by topology which allows for better signal integrity but at the same time requires additional calibration.

nb/intel/x4x: Add DDR3 JEDEC init
Arthur Heymans: Add DDR3 JEDEC init (Power up and Initialization by setting emrs regs)

src: Add space after 'while'
Elyes HAOUAS

chromeec: Add support for controlling USB port power
Emil Lundmark: This maps a bit field to the EC (EC_ACPI_MEM_USB_PORT_POWER) that can be used to control the power state of up to 8 individual USB ports.

mb/google/poppy: Enable SAR config on Nami
Amanda Huang: This change enables SAR config on Nami with CHROMEOS option.

Yesterday's Activity

mb/google/kahlee/dsdt.asl: Add method _SWS
Richard Spiegel: _SWS is the recommended method of wake source retrieval.

mb/google/poppy/variants/nocturne: enable I2C #5 bus
Nick Vaccaro: Enable I2C #5 for rear camera and SAR.

mb/google/poppy/variants/nocturne: add touchscreen register info
Nick Vaccaro: - add ACPI register information for touchscreen WCOM digitizer

Other Activity This Week

Documentation: Update doxygen config files
Martin Roth: - Update the config files to 1.8.13- Unify the coreboot and coreboot_simple configs.

soc/nvidia/tegra(124|210): Add distclean targets
Martin Roth: Add distclean targets so these can be called by the junit.xml test target needed for jenkins testing.

rk3399: Enable bootblock compression
Julius Werner: This patch enables the new bootblock compression feature on RK3399, which requires moving MMU initialization into the decompressor stage and linking the decompressor (rather than the bootblock) into the entry point jumped to by the masked ROM. RK3399's masked ROM seems to be using a bitbang SPI driver to load us (very long pauses between clocking in each byte), with an effective data rate of about 1Mbit.

Introduce bootblock self-decompression
Julius Werner: Masked ROMs are the silent killers of boot speed on devices without memory-mapped SPI flash.

cbfs-compression-tool: Add raw compression support
Julius Werner: This patch adds a new "rawcompress" command to cbfs-compression-tool, that works exactly the same as "compress" except that it doesn't add the custom 8-byte header to the file.

mb/google/octopus: Add devicetree for Bip
Justin TerAvest: Bip should have different devicetree entries than Yorp; it doesn't have a DA7219 audio codec (instead it uses ALC5682).

util/testing: Update junit.xml to support coreboot builds
Martin Roth: Up to this point, junit.xml has only been used to build tools, as abuild has handled the coreboot builds.

Documentation: Add lesson1 from the wiki
Martin Roth: Convert the lesson1 document from the wiki to markdown, update it for Ubuntu 18.04, and extend it slightly with new information.

cpu/x86: Add support to run function on single AP
Subrata Banik: This patch ensures that user can select a specific AP to run a function.

soc/intel/cannonlake: Add CONFIG_SMM_RESERVED_SIZE config
Subrata Banik: This patch ensures to make SMM_RESERVED_SIZE for cannonlake platform else smm_subregion() returns 0 size.

soc/amd/stoneyridge: Support ACPI USB code generation
Duncan Laurie: To support generating USB devices in ACPI the platform needs to know how to determine a device name for each USB port, and for any root hubs that may be present. The AMD Stoney Ridge platform has separate controllers for USB 2.0 and USB 3.0.

soc/intel: Add support for USB ACPI code generation
Duncan Laurie: To support generating USB devices in ACPI the platform needs to know how to determine a device name for each USB port, and for any root hubs that may be present. Recent Intel platforms route all ports to an XHCI controller through a root hub.

drivers/usb/acpi: Add a driver for generating USB ACPI
Duncan Laurie: Add a support for generating USB port descriptors for ACPI based on their definition by the board in devicetree.cb.

nb/common/intel: Remove the mrc cache code
Arthur Heymans: This is now unused, since all intel northbridges now use the equivalent in drivers/mrc_cache.

Coreboot Release Tags

ifdtool: Add a list of known platforms that support IFD_VERSION_2
Furquan Shaikh: ifdtool has relied on one of the fields within FCBA(read_freq) to determine whether a platform supports IFD_VERSION_1 or IFD_VERSION_2.

vendorcode/intel: Add Kconfig option to get UDK_VERSION
Subrata Banik: This patch ensures if required SoC/FSP driver code can retrieve UDK version for a platform.

soc/intel/cannonlake: Select SOC_INTEL_COMMON_BLOCK_GSPI_VERSION_2
Furquan Shaikh: BUG=b:70628116

soc/intel/common/block/gspi: Add SOC_INTEL_COMMON_BLOCK_GSPI_VERSION_2
Furquan Shaikh: Even though kaby lake and cannon lake are using the same GSPI controller, bit meanings (for polarity and state) in SPI_CS_CONTROL register are significantly different.

SeaBIOS: remove VERSION variable in coreboot Makefile
Alexander Couzens: SeaBIOS dropped support of VERSION variable and is reproducible without it.

buildgcc: use ${GDB_DIR} instead of gdb-${GDB_VERSION}
Stefan Reinauer: Bring gdb in sync with all other build targets.

lenovo/*: Remove unused MAINBOARD_VERSION
Vladimir Serbinenko: Change-Id: I88e889efe43b32e7efc59ea40d13e79209a27264

acpi: Add support for generating ACPI _UPC
Duncan Laurie: This commit adds support for writing ACPI _UPC structures that help describe USB ports for the OS. This is a simple structure format which indicates what type of port it is and whether it is connectable.

libpayload-x86: Add common i8042 driver
Patrick Rudolph: Add a common i8042 driver that uses multiple overflowing fifos to seperate PS/2 port and PS/2 aux port.

msrtool: add support for printing string values
Lubomir Rintel: The VIA CPUs allow setting the CPUID vendor, which is best read as a character string.

Documentation: SandyBridge_registers.md: Add a title
Jonathan Neuschäfer: This fixes the following error when using "make -C Documentation sphinx":

msrtool: add VIA C7
Lubomir Rintel

sdm845: Add Timer support
T Michael Turney: Frequency set to 19.2 MHz

Documentation: Add support for building with Sphinx
Jonathan Neuschäfer: This commit adds the necessary infrastructure to convert the Markdown files in the Documentation directory to HTML using Sphinx[1] and recommonmark[2].

device: Add flag to disable PCIe ASPM
Nico Huber: For broken devices that spuriously advertise ASPM, make it possible to decide ASPM activation in the device driver.

libpayload-x86: Add PS2 mouse driver
Patrick Rudolph: Make use of i8042 driver to add PS2 mouse driver support. Tested on Lenovot T500.
