Hi Simon Yes that fixes it! Thanks! Maybe an Idea to add a dedicated TPM page to the docs with information like this? (https://u-boot.readthedocs.io/en/latest/index.html) Cause I wouldn't have thought I needed an option tugged away under Library routines.
Anyhow Thanks!

Anyhow thanks for the help! You can edit the defconfig to add CONFIG_TPM and whatever driver you need.
