2023-07-30sb/intel/lynxpoint/me: Use C99 flexible arraysElyes Haouas
Use C99 flexible arrays instead of older style of one-element or zero-length arrays. It allows the compiler to generate errors when the flexible array does not occur at the end in the structure.

2022-12-23sb/intel/lynxpoint: Add Kconfig option to hide Intel MEMatt DeVillier
On lynxpoint devices, coreboot currently disables and hides the ME PCI interface by default, without any way to opt out of this behavior. Add a Kconfig option to allow for leaving the ME PCI interface enabled, but set the default to disabled as to leave the current behavior unchanged.

2022-03-07src: Make PCI ID define names shorterFelix Singer
Shorten define names containing PCI_{DEVICE,VENDOR}_ID_ with PCI_{DID,VID}_ using the commands below, which also take care of some spacing issues. An additional clean up of pci_ids.h is done in CB:61531. Used commands: * find -type f -exec sed -i 's/PCI_\([DV]\)\(EVICE\|ENDOR\)_ID_\([_0-9A-Za-z]\{2\}\([_0-9A-Za-z]\{8\}\)*[_0-9A-Za-z]\{0,5\}\)\t/PCI_\1ID_\3\t\t/g' * find -type f -exec sed -i 's/PCI_\([DV]\)\(EVICE\|ENDOR\)_ID_\([_0-9A-Za-z]*\)/PCI_\1ID_\3/g' Change-Id: If9027700f53b6d0d3964c26a41a1f9b8f62be178 Signed-off-by: Felix Singer <felixsinger@posteo.net> Reviewed-on: https://review.coreboot.org/c/coreboot/+/39331 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Michael Niewöhner <foss@mniewoehner.de>

2021-11-04sb/intel: Replace bad uses of `find_resource`Angel Pons
The `find_resource` function will never return null (will die instead). In cases where the existing code already accounts for null pointers, it is better to use `probe_resource` instead, which returns a null pointer instead of dying.

2021-04-21ChromeOS: Use CHROMEOS_NVS guardKyösti Mälkki
Replace CONFIG(CHROMEOS) with CONFIG(CHROMEOS_NVS) for cases where the conditional and dependency are clearly about the presence of an ACPI NVS table specified by vendorcode. For couple locations also CONFIG(HAVE_ACPI_TABLES) changes to CONFIG(CHROMEOS_NVS). This also helps find some of the CONFIG(CHROMEOS) cases that might be more FMAP and VPD related and not about ChromeOS per-se, as suggested by followup works.
