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 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. Rebased onto latest tpmdd/master. Changes in v3: 1. Update patch #2 to support registration of multiple kernel pages. 2. Incoporate dependency patch #4 in this patch-set: https://patchwork.kernel.org/patch/11091435/ Changes in v2: 1. Add reviewed-by tags for patch #1 and #2. 2. Incorporate comments from Jens for patch #3. 3. Switch to use generic trusted keys framework.
