2024-01-31include/device/device.h: Remove CHIP_NAME() macroNicholas Sudsgaard
Macros can be confusing on their own; hiding commas make things worse. This can sometimes be downright misleading. A "good" example would be the code in soc/intel/xeon_sp/spr/chip.c: CHIP_NAME("Intel SapphireRapids-SP").enable_dev = chip_enable_dev, This appears as CHIP_NAME() being some struct when in fact these are defining 2 separate members of the same struct. It was decided to remove this macro altogether, as it does not do anything special and incurs a maintenance burden.

2024-01-24driver/acpi to /driver/gfx: Rename Makefiles from .inc to .mkMartin Roth
The .inc suffix is confusing to various tools as it's not specific to Makefiles. This means that editors don't recognize the files, and don't open them with highlighting and any other specific editor functionality. This issue is also seen in the release notes generation script where Makefiles get renamed before running cloc.

2023-08-06drivers: Add SPDX license headers to MakefilesMartin Roth
To help identify the licenses of the various files contained in the coreboot source, we've added SPDX headers to the top of all of the .c and .h files. This extends that practice to Makefiles. Any file in the coreboot project without a specific license is bound to the license of the overall coreboot project, GPL Version 2. This patch adds the GPL V2 license identifier to the top of all makefiles in the drivers directory that don't already have an SPDX license line at the top.

Some of the chip.h files in the tree are missing the include guards. This patch adds them in order to avoid potential redefinions of symbols contained in these headers, when they are included multiple times in static.c generated by sconfig.

2022-08-17pciexp_device: Join pciexp_find_(next_)extended_cap() APIsNico Huber
Move the `offset` parameter into pciexp_find_extended_cap(). If it's called with `0`, we start a new search. If it's an existing offset, we continue the search. This makes it easier to search for multiple occurences of a capa- bility in a single loop.

Shorten define names containing PCI_{DEVICE,VENDOR}_ID_ with PCI_{DID,VID}_ using the commands below, which also take care of some spacing issues.

2021-12-22drivers/generic/bayhub_lv2: Work around known errataTim Wawrzynczak
The Bayhub LV2 has a known errata wherein PCI config registers at offsets 0x234, 0x238, and 0x24C will only correctly accept writes when they are addressed via a DWORD (32-bit) wide write operation on the PCIe bus. Offset 0x234 is the LTR max snoop and max no-snoop latency register, therefore add a finalize callback to this driver which will program the LTR max-snoop/no-snoop register with a 32-bit write using the values from pciexp_get_ltr_max_latencies().

2021-02-20drivers/generic/bayhub_lv2: remove unnecessary configsVictor Ding
coreboot sets up CLK_PM, ASPM, and L1ss automatically based on related bits in "Link Capability Register" and "L1 PM Substates Capabilities Register". coreboot overrides these configs even if the driver sets them. Therefore, setting up CLK_PM, ASPM, and L1ss in the driver is redundant and useless.

2021-02-20drivers/generic/bayhub_lv2: move the driver to ".enable"Victor Ding
coreboot sets up certain configs (e.g. L1ss) based on the device's reported capacities; however, this BayHub lv2 driver modifies some of its capacities after coreboot uses them. Therefore, coreboot may make incorrect configs based on out-of-date capacities. This patch moves the driver from ".init" to ".enable" so that the capacities are set before the rest of coreboot queries them.
