🔐 Security Impacting

[TPM][FF-A] Yield Updates for TPM Service @Raymond-MS (#64)

Change Details

Description

Add yielding capability for long running transactions such that we are not held up in the secure-world for extended periods of time. Yields control back to the NWd with a timeout value for when the secure partition (TPM service) should be run again. This allows us to check the register contents periodically while allowing execution in the NWd to continue.
