	coreboot uses TianoCore interchangeably with EDK II, and whilst the meaning is generally clear, it's not the payload it uses. EDK II is commonly written as edk2. coreboot builds edk2 directly from the edk2 repository. Whilst it can build some components from edk2-platforms, the target is still edk2. [1] tianocore.org - "Welcome to TianoCore, the community supporting" [2] tianocore.org - "EDK II is a modern, feature-rich, cross-platform firmware development environment for the UEFI and UEFI Platform Initialization (PI) specifications."

	SMMSTORE version 2 is a complete redesign of the current driver. It is not backwards-compatible with version 1, and only one version can be used at a time. Key features: * Uses a fixed communication buffer instead of writing to arbitrary memory addresses provided by untrusted ring0 code. * Gives the caller full control over the used data format. * Splits the store into smaller chunks to allow fault tolerant updates. * Doesn't provide feedback about the actual read/written bytes, just returns error or success in registers. * Returns an error if the requested operation would overflow the communication buffer. Separate the SMMSTORE into 64 KiB blocks that can individually be read/written/erased. To be used by payloads that implement a FaultTolerant Variable store like TianoCore. The implementation has been tested against EDK2 master. An example EDK2 implementation can be found here: https://github.com/9elements/edk2-1/commit/eb1127744a3a5d5c8ac4e8eb76f07e79c736dbe2 Change-Id: I25e49d184135710f3e6dd1ad3bed95de950fe057 Signed-off-by: Patrick Rudolph <patrick.rudolph@9elements.com> Signed-off-by: Christian Walter <christian.walter@9elements.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/40520 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Michał Żygowski <michal.zygowski@3mdeb.com> Reviewed-by: Matt DeVillier <matt.devillier@gmail.com>
