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.

2020-05-02acpi: Move ACPI table support out of arch/x86 (3/5)Furquan Shaikh
This change moves all ACPI table support in coreboot currently living under arch/x86 into common code to make it architecture independent. ACPI table generation is not really tied to any architecture and hence it makes sense to move this to its own directory. In order to make it easier to review, this change is being split into multiple CLs. This is change 3/5 which basically is generated by running the following command: $ git grep -iIl "arch/acpi" | xargs sed -i 's/arch\/acpi/acpi\/acpi/g' BUG=b:155428745 Change-Id: I16b1c45d954d6440fb9db1d3710063a47b582eae Signed-off-by: Furquan Shaikh <furquan@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/40938 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: HAOUAS Elyes <ehaouas@noos.fr>

2016-07-08acpi: Change device properties to work as a treeDuncan Laurie
There is a second ACPI _DSD document from the UEFI Forum that details how _DSD style tables can be nested, creating a tree of similarly formatted tables. This document is linked from acpi_device.h. In order to support this the device property interface needs to be more flexible and build up a tree of properties to write all entries at once instead of writing each entry as it is generated. In the end this is a more flexible solution that can support drivers that need child tables like the DA7219 codec, while only requiring minor changes to the existing drivers that use the device property interface. This was tested on reef (apollolake) and chell (skylake) boards to ensure that there was no change in the generated SSDT AML.
