Cover letter [U-Boot] [PATCH 00/18] Introduce SPI TPM v2.0 support
Quoted 8 lines · Miquel Raynal

Current U-Boot supports TPM v1.2 specification. The new specification (v2.0) is not backward compatible and renames/introduces several functions.

This series introduces a new SPI driver following the TPM v2.0 specification. It has been tested on a ST TPM but should be usable with others v2.0 compliant chips.

Quoted 5 lines

Then, basic functionalities are introduced one by one for the v2.0 specification. The INIT command now can receive a parameter to distinguish further TPMv1/TPMv2 commands. After that, the library itself will know which one is pertinent and will return a special error if the desired command is not supported for the selected specification.

Thanks for doing all of this. Can you please enable this feature on sandbox and/or an x86 QEMU variant where I assume we could also then setup automated testing?
