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.

2023-05-03drivers/sof: Add new driver to generate ACPI _DSD tableMatt DeVillier
Add a new chip driver for boards which use SOF (Sound Open Firmware) OS drivers, which will be attached to the HDAS device and generate entries in an ACPI _DSD table for the OS driver to use. This will allow the OS drivers to easily determine the correct topology for the speaker and jack amplifiers and correct microphone configuration.
