First motivation was to fix failures coming from too short timeouts for commands that creates keys. Key generation may take significant time depending on the underlying hardware. Rather than increasing default timeout a new constant is added, to not stall too long on regular commands failures. Second is to define timeouts for new tpm2 commands defined in TCG 1.36 spec. Tomas Winkler (5): tpm: sort objects in the Makefile tpm: factor out tpm 1.2 duration calculation to tpm1-cmd.c tpm2: add longer timeouts for creation commands. tpm2: add new tpm2 commands according to TCG 1.36 tmp: factor out tpm_get_timeouts V2: 1. Makefile go back tpm-y construct. 2. Add more info to longer timouts patch 3. Rebase other patches 4.
