The TPM code was added more than a year or 4 releases ago. This was done under the proposition that board support that would actually use such code would be added soon. However, nothing happened since. The code has no users in mainline, and does not even get build for any configuration, so we cannot even tell if it compiles at all.
Remove the unused code. In in some far future actual users show up, it can be re-added easily.
I think you may have missed the pending patches which make use of this. it is important functionality for the Chromebooks (secure boot).
No, I have not missed these. But all the patch does is set CONFIG_GENERIC_LPC_TPM - there is still not a single user defining CONFIG_CMD_TPM, so what does this help? We still have tons of dead code around. Dump it!
Best regards,
