Also, this is an alternative in case platform doesn't possess a TPM device. This series also adds some TEE features like: Patch #1, #2 enables support for registered kernel shared memory with TEE. Patch #3 enables support for private kernel login method required for cases like trusted keys where we don't wan't user-space to directly access TEE service to retrieve trusted key contents. Rest of the patches from #4 to #7 adds support for TEE based trusted keys. This patch-set has been tested with OP-TEE based pseudo TA which can be found here [1]. Looking forward to your valuable feedback/suggestions.
