Is it possible to implement the TPM2.0 (Trusted Platform Module) standard with the security controller in iMX8, or are there TPM functions that need an external TPM chip?
"We're not aware of any NXP activities to support directly the TPM specification. But taking a look at internal Community, seems, that it is possible to connect the TPM using the I2C bus (SMBUS can be controlled via 2-wire interface which is basically similar with I2C - here [1] you have a datasheet explained that).
