[PATCH 0/3] Add support for TPM devices over I2C bus

Posted by Ninad Palsule 1 year, 1 month ago

This drop adds support for the TPM devices attached to the I2C bus. It
only supports the TPM2 protocol. You need to run it with the external
TPM emulator like swtpm. I have tested it with swtpm.

I have refered to the work done by zhdaniel@meta.com but at the core
level out implementation is different.
