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.

2023-06-01drivers/ocp/vpd: Overwrite Linux payload's kernel command via VPDJohnny Lin
Add a new Kconfig LINUXPAYLOAD_CMDLINE_VPD_OVERWRITE that can overwrite Linux payload's kernel command line from VPD. Currently only overwrite Linux kernel command line 'loglevel' via VPD key 'kernel_log_level'. TESTED=On OCP Delta Lake, with kernel_log_level set to 0, warm reboot time can see about 10 seconds improvement comparing to kernel log level 7.

2023-02-16drivers/ocp/vpd: Override mainboard_set_smm_log_levelJohnny Lin
VPD variable 'smm_log_level' can be read and passed to SMM for overriding SMM log level. By default it's zero therefore it disables most of the SMM log. When we need to see SMM log we can set this VPD to a larger value to enable it. Implement mainboard_set_smm_log_level() that reads VPD variables for SMM log level.

This reverts commit 059902882ce56502124375c9395ebe8b49640710. A dependency of the previous patch that added the get_ewl_hob function used by this patch was missing, so this patch needs to be temporary reverted to revert the patch that breaks the build due to the missing dependency.
