Hello Aaron Durbin, Roy Wen, David Hendricks, Philipp Deppenwiese, build bot (Jenkins), Nico Huber, Patrick Georgi, Martin Roth, Jens Drenhaus,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/31548

to look at the new patch set (#5).

Change subject: security: Add memory subfolder
......................................................................

security: Add memory subfolder

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.
