Add support for TEE based trusted keys where TEE provides the functionality
to seal and unseal trusted keys using hardware unique key. 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/f86ab8e7e0de869...
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.
