	_STR should return Unicode string. From ACPI spec: 6.1.10 _STR (String) The _STR object evaluates to an Unicode string that describes the device or thermal zone. BUG=NA TEST=Check the changed _STR in SSDT to see if Unicode() macro is used Signed-off-by: Cliff Huang <cliff.huang@intel.com> Change-Id: I1f4b55a268c1dadbae456afe5821ae161b8e15a5 Reviewed-on: https://review.coreboot.org/c/coreboot/+/77695 Reviewed-by: Eric Lai <eric_lai@quanta.corp-partner.google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Jérémy Compostella <jeremy.compostella@intel.com>
2023-08-06	drivers: Add SPDX license headers to Makefiles	Martin 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.
