2023-08-14commonlib,console,nb,sb,security: Add SPDX licenses 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 commonlib, console, northbridge, security, and southbridge directories that don't already have an SPDX license line at the top.

2019-07-02security/memory: Clear memory in ramstagePatrick Rudolph
* Add architecture independend way of clearing all DRAM * Implemented in ramstage as MTRRs need to be set to speed up clearing. Takes up to 15 seconds per GiB otherwise. * Use memset_pae on x86 * Add quirks for FSP1.0 Tested on P8H61M-Pro: * Clears 4GiB in less than 1 second Tested on wedge100s: * Clears 8GiB in 2 seconds Change-Id: Idaadb8fb438e5b95557c0f65a14534e8762fde20 Signed-off-by: Patrick Rudolph <patrick.rudolph@9elements.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/31550 Reviewed-by: Philipp Deppenwiese <zaolin.daisuki@gmail.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
2019-06-27security: Add memory subfolderPatrick Rudolph
Add files to introduce a memory clearing framework. Introduce Kconfig PLATFORM_HAS_DRAM_CLEAR that is to be selected by platforms, that are able to clear all DRAM. Introduce Kconfig SECURITY_CLEAR_DRAM_ON_REGULAR_BOOT that is user selectable to always clear DRAM on non S3 boot. The function security_clear_dram_request tells the calling platform when to wipe all DRAM. Will be extended by TEE frameworks. Add Documentation for the new security API.
