While doing bringup/rebase for the Ten64 I did some troubleshooting for the tpm (v1.2, NOT tpm2) command which did not appear to function, despite the Linux driver and tools (tcsd) working on the same board.
Evidently the Atmel TPM driver hasn't kept up with various step changes in the I2C and TPM stacks, and while TPMv1.2 is quite dated to TPMv2 it would be nice to make some use of the hardware that is there. (Admittedly I would love to replace our hardware TPM with an fTPM but that is a project for another day)
There are also subcommands in tpm-v1 which also have been missed in changes to the TPMv1 API and are fixed in this patchset.
I have checked that this set isn't impacted by Ilias' TPM cleanup series[1] which only touches TPMv2.
