Subrata Banik 0f90c5d5f9 security/tpm: Retrieve factory configuration for device w/ Google TPM ... This patch enables retrieval of factory configuration data from Google TPM devices (both Cr50 and Ti50). This patch utilizes vendor-specific command TPM2_CR50_SUB_CMD_GET_FACTORY_CONFIG (68). The factory config space is a 64-bit, one-time programmable. For the unprovisioned one, the read will be 0x0. BUG=b:317880956 TEST=Able to retrieve the factory config from google/screebo.
