U-Boot support for wolfTPM and firmware update for SLB9672/SLB9673

[David Garske]

Hi Denx,

We at wolfSSL have developed a port for wolfTPM in U-Boot. The patch allows using the current built-in TPM 2.0 support or switching to wolfTPM via CONFIG_TPM_WOLF=y. It also supports TPM 2.0 firmware update for the Infineon SLB9672 and SLB9673.

I think there is probably some more cleanup and testing needed, but I wanted to submit this to start the discussion and see your thoughts.

The wolfTPM library is GPLv2 and added as a submodule. If the license or submodule is an issue let’s discuss! I’m positive we can resolve anything.

Attached is the patch based on latest master 3b6760ddeb4 to review.



Thanks,
