[PATCH v4 00/14] tpm: Add wolfTPM library support for TPM 2.0

[Aidan Garske]

Hi all, 

Yes we have moved all our libraries to GPLv3. We have made exceptions for some open source projects to allow GPLv2 see here: https://github.com/wolfSSL/wolfssl/blob/master/LICENSING#L8. We are willing to do this for wolfTPM and DENX/U-Boot.

Thanks, 
Aidan
