Hi James,

Sorry, I pressed send before writing anything. Here is the summary:

* Migrated away from PM runtime as explicit cmdReady/goIdle trasactions for every command is a spec requirement. PM runtime adds only a layer of complexity on our case.
* tpm_tis drivers can now specify the hwrng quality.
* TPM 2.0 code uses now tpm_buf for constructing messages. I think Tomas Winkler has done the same for TPM 1.2. I'll start digging those changes from the patchwork in the near future.
* Bug fixes and clean ups.

/Jarkko
