Also, this is an alternative in case platform doesn't possess a TPM device. This patch-set has been tested with OP-TEE based early TA which is already merged in upstream [1]. [1] https://github.com/OP-TEE/optee_os/commit/f86ab8e7e0de869dfa25ca05a37ee070d7e5b86b Changes in v6: 1. Revert back to dynamic detection of trust source. 2. Drop author mention from trusted_core.c and trusted_tpm1.c files. 3. Rebased to latest tpmdd/master. Changes in v5: 1. Drop dynamic detection of trust source and use compile time flags instead. 2. Rename trusted_common.c -> trusted_core.c. 3. Rename callback: cleanup() -> exit(). 4. Drop "tk" acronym. 5. Other misc. comments. 6. Added review tags for patch #3 and #4. Changes in v4: 1. Pushed independent TEE features separately: - Part of recent TEE PR: https://lkml.org/lkml/2020/5/4/1062 2. Updated trusted-encrypted doc with TEE as a new trust source. 3.
