QuarkPlatformPkg/Tpm12DeviceLibAtmelI2c: Remove PP Check https://bugzilla.tianocore.org/show_bug.cgi?id=337 The Tpm12CommandLib in the SecurityPkg was updated to check the returnCode in the response packet in the following commit: https://github.com/tianocore/edk2/commit/950a3bc788b5b101729b26aed3ff75fd2a64a570 The Tpm12DeviceLibAtmelI2C uses the Tpm12PhysicalPresence() function from the Tpm12CommandLib to verify that the I2C device is responding to TPM command packets. However, at this point the TPM device has not been started, and the TPM properly responds with an error in the returnCode field of the response packet. Before the commit above, the check worked, but the additional error checking in the commit above now returns an error and an Atmel I2C is returned as not present. The fix is to remove the call to the Tpm12PhysicalPresence() API in the Tpm12CommandLib from the Tpm12RequestUseTpm() API. The Atmel I2C TPM device is detected if a byte can be read from the slave address assigned to the Atmel I2C device. When the startup command is sent to the TPM later, the command and response packet processing will be verified, and if the I2C device is not an Atmel TPM, it will be detected at that point.
